Can't launch JOSM.app on macOS with OpenJDK installed, instead of JRE from Oracle.

[molind]

I'm using OpenJDK during my work and keep it as only available java on my macOS. It's installed using 'brew cask install java'. After that java is available in Terminal:

evgen@Evgens-iMac Java % java --version
openjdk 13.0.1 2019-10-15
OpenJDK Runtime Environment (build 13.0.1+9)
OpenJDK 64-Bit Server VM (build 13.0.1+9, mixed mode, sharing)

I could launch: java --jar josm-snapshot-15492.jar using snapshot bundled inside JOSM.app, but when I'm trying to launch JOSM.app itself it shows an error: JRE load error as window. When i launch it from termital i see following:

evgen@Evgens-iMac MacOS % ./JOSM

Seems an additional option required for <bundleapp> in build.xml to correctly detect JRE in runtime.

Probably a side effect of the issues listed there: ​https://github.com/teras/appbundler/issues

If you're a Java developer working on Mac, maybe you know what needs to be fixed? I have too little knowledge of how macOS works to fix this issue right now.

Note that OpenJDK is working on a new tool in Java 14 to package applications: ​https://openjdk.java.net/jeps/343

[molind]

I've used appbundler from ​https://github.com/TheInfiniteKind/appbundler/ instead of provided in tools folder and it worked.

It worked without issues on my machine with OpenJDK 13.0.1 but it worked with multiple exceptions when my colleague launched on machine with Java 1.8 1.8.0_181-b13. I think it's because of JRE version mismatch. When old version of JRE used to run code from newer JRE.

Maybe JOSM.app should include JRE used to build the app?

Where is the binary? I don't see any release on this repo.

Can you please report the issues to the author? If we switch to it still must be compatible with java 8.

It shouldn't be necessary.

I just built it using ant.

Just to be clear. It wasn't appbundler issue, but JOSM issue.

Okay. I'll submit crashes right away. And post links right there.

[Stereo]

The advantages of switching to OpenJDK on Retina displays are so considerable (see #18720) that I think it would make sense to jump to supporting only OpenJDK, and closing this ticket with the proposed fix despite all of the flaws it currently has.

A temporary workaround is to launch josm from the command line, java -jar /Applications/JOSM.app/Contents/Java/josm-*.jar

[Don-vip]

Replying to Stereo:

Beware, the improvements you see are due to your switch from Java 8 to Java 13, which contains a lot of HIDPI improvements. You would have seen the same improvements with an Oracle runtime. They are 99.99% identical.

It doesn't mean however we will continue to support Oracle runtime. At the end of the year, the Java 8 Oracle binaries will no longer be provided to Windows and mac users. See #17858 for the switch to OpenWebStart/AdoptOpenJDK/Java 11.

[Stereo]

Aha! I'll brew install oracle-jdk in the meanwhile then.

[Stereo]

All right, it turns out there's no Oracle JRE beyond Java 8 for macOS, as far as I can tell. Installing just the Oracle 13 JDK produces the same JRELoadError.

It seems like the best path would be for JOSM to support launching from a preinstalled openjdk 13 bundle, or indeed to bundle its own JRE.

[Stereo]

The freshly released Java 14 now has a nice new bundler.

[anonymous]

Sounds great! Do you need any assistance to try it on macOS?

[molind]

Last message was mine. Let me know if I could help to check it on macOS Catalina.

[ryandesign]

JOSM was just ​submitted to MacPorts and I approved the submission even though the problem reported in this ticket also happened to me during testing. On my system:

Hopefully you can solve this problem and release a new version so that we can update to that in MacPorts so that our users won't experience this issue.

[dr.snaglers@…]

I've resolved the issue by using brew and OpenJDK 11.

brew cask install josm
brew cask install java11

OSM Jar downloaded by brew : josm-snapshot-16239.jar

java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

[Stereo]

I'm not sure what your setup is or if you have an extra homebrew tap? Here's what I'm getting:

> brew cask install java11
Error: Cask 'java11' is unavailable: No Cask with this name exists.

Did you mean brew install java11?

[Stereo]

I'm still getting JRELoadError with the java11 formula installed. You might still have Oracle Java installed - what does the JOSM about window say?

[anonymous]

Hello,

I'm not sure, if I've added another cask in the past. How do I find out?

However, I'm certain I've installed the JRE with following command:

brew cask install java11

And

brew cask info java11 says:
java11: 11.0.2,9
​https://www.oracle.com/technetwork/java/javase/
/usr/local/Caskroom/java11/11.0.2,9 (148B)
From: ​https://github.com/Homebrew/homebrew-cask-versions/blob/master/Casks/java11.rb
==> Name
OpenJDK Java Development Kit
==> Artifacts
jdk-11.0.2.jdk -> /Library/Java/JavaVirtualMachines/openjdk-11.0.2.jdk (Generic Artifact)

Furthermore, JOSM About says I'm using following Java Home:
/Library/Java/JavaVirtualMachines/openjdk-11.0.2.jdk/Contents/Home

Anyway, the solution is to not use last Java version (14). That's what JOSM says, it isn't compatible. In general, it's more save to go with Java 11, since it's long term support version, therefore, supported by most applications.

[anonymous]

Hi again,
I've found from where I've installed this version of JRE.

It's from homebrew/cask-versions

Therefore, the complete installation instruction would be:

brew tap homebrew/cask-versions
brew cask install java11
brew cask install josm

For more information see : ​https://github.com/Homebrew/homebrew-cask-versions

Have fun!

[Stereo]

All right, that explains it. That java11 cask installs ​https://download.oracle.com/java/GA/jdk11/9/GPL/openjdk-11.0.2_osx-x64_bin.tar.gz so not openjdk but oracle.

It's a valuable workaround, but not a fix.

[Stereo]

I've played with jpackage a bit, and it looks quite promising. I have a JOSM.app that includes the OpenJDK 14 JRE and runs quite well.

I've used /Library/Java/JavaVirtualMachines/openjdk-14.0.1.jdk/Contents/Home/bin/jpackage -n "JOSM" --input dist --main-jar josm-custom.jar --main-class org.openstreetmap.josm.gui.MainApplication --icon ./native/macosx/JOSM.icns --type app-image --dest appimageoutput --java-options "-Xmx8192m" --app-version "16539" --copyright "JOSM, and all its integral parts, are released under the GNU General Public License v2 or later" --vendor "https://josm.openstreetmap.de" --file-associations native/macosx/bz2.properties --file-associations native/macosx/geojson.properties --file-associations native/macosx/gpx.properties --file-associations native/macosx/gz.properties --file-associations native/macosx/jos.properties --file-associations native/macosx/joz.properties --file-associations native/macosx/osm.properties --file-associations native/macosx/zip.properties --add-modules java.base,java.datatransfer,java.desktop,java.logging,java.management,java.naming,java.net.http,java.prefs,java.rmi,java.scripting,java.sql,java.transaction.xa,java.xml,jdk.crypto.ec,jdk.jfr,jdk.jsobject,jdk.unsupported,jdk.unsupported.desktop,jdk.xml.dom

The properties files basically look like:

extension=osm
mime-type=application/x-osm+xml
icon=native/macosx/JOSM.app/Contents/Resources/JOSM.icns
description=JOSM File

What doesn't work yet:

• Done: I only tell it that it can open .osm and .gpx files, basically out of laziness. Every file type needs a .properties file.
• Done: There are no icons for the gpx and osm files. Giving it the path to JOSM.icns in the .properties file causes an error ("java.nio.file.FileAlreadyExistsException: appimageoutput/JOSM.app/Contents/Resources/JOSM.icns") and a blank icon for JOSM.app. Hey, maybe I can finally create icons for .osm files on macOS :)
• Done and shrunk to 36.9M zipped: It includes *all* of the JRE, so the .app is a humongous 147MB. [jlink can be used to produce a jre with only the necessary parts](​https://www.baeldung.com/jlink). Not including a JRE is, apparently, not possible. Considering how much of a pain it is to install Java and to debug different JREs, this might actually be a good thing
• Building only works on macOS, and the JOSM builds are currently only built on Linux.
• Done thanks to Thomas Skowron's help: No code signature yet. Opening the app will say that is is damaged. Run xattr -d com.apple.quarantine JOSM.app.

Wanna test? ​https://openstreetmap.lu/JOSM.zip has this very raw first preview.

[Stereo]

JOSM icons for macOS, created with docerator.py --appicon /Applications/JOSM.app/Contents/Resources/JOSM.icns --text OSM etc.

[Stereo]

It looks like macOS auto-generates good enough document images if we let it, so let's scratch that :)

[Stereo]

Optimised JOSM.icns for macOS: crushed PNG, removed unnecessary sizes

[Stereo]

.properties file to be used for packaging

[Stereo]

So it looks like all the known issues are taken care of. We'll always need macOS to run for signing, but something like GitHub Actions could do that on every commit.

​https://openstreetmap.lu/JOSM.zip is the latest test build. Please try it out and let me know.

Currently, we're already using 3 different CI systems:

• https://josm.openstreetmap.de/jenkins/
• ​https://travis-ci.org/github/openstreetmap/josm (using the GitHub mirror)
• ​https://ci.appveyor.com/project/don-vip/josm (using the GitHub mirror)

Can anyone of those be configured for this purpose?

[Don-vip]

Replying to simon04:

• ​https://travis-ci.org/github/openstreetmap/josm (using the GitHub mirror)

I guess we should transfer this one to JOSM organization and start to use it for producing such native apps.

[Stereo]

It looks like ​https://docs.travis-ci.com/user/reference/osx/ could work.

[Stereo]

We don't seem to be using Travis for anything other than ant tests:

​https://github.com/openstreetmap/josm/blob/master/.travis.yml

I'd be just as happy to rewrite those in github actions.

[Stereo]

Rewritten Travis ant tests as GitHub Actions:

​https://github.com/grischard/josm/blob/master/.github/workflows/ant.yml

Preliminary results are here: ​https://github.com/grischard/josm/runs/757124064?check_suite_focus=true

It fails on creating a RELEASE.xml which is the same as ​https://lists.openstreetmap.org/pipermail/josm-dev/2014-February/006898.html but I'm not sure how to fix it. Maybe simon04 has an idea?

[simon04]

Six years have passed since I wrote this part in the build file, see r6545. Maybe you can execute the command separately to see if it is working. Some time ago, I tested the following build based on a sparse checkout: ticket:6887#comment:51

[simon04]

The problem is that GitHub Actions fetches the repository using --depth=1. Since the latest commit is a non-git-svn commit, no SVN revision can be obtained:

$ git init
$ git remote add origin https://github.com/grischard/josm
$ git -c protocol.version=2 fetch --no-tags --prune --progress --no-recurse-submodules --depth=1 origin
$ git log origin/master 
commit 13739d01139edfcd0b5adb69fb811a490ce837a8 (grafted, origin/master)
Author: Guillaume Rischard <github@stereo.lu>
Date:   2020-06-10 10:48:51 +0200

    Say the same thing but more simply
<only one commit>
$ git log origin/master -1 --grep=git-svn-id 
<nothing>

You may want to increase the fetch-depth as documented on ​https://github.com/actions/checkout#fetch-all-history-for-all-tags-and-branches
Maybe fetch-depth: 32 is sufficient, assuming that there are no more than 32 commits after the latest git-svn commit.

The Github Actions now builds, packages and uploads a JOSM.app.

[Robert Floor]

Hi all, I am still seeing the JRELoadError in josm-macosx-16812. Should it be solved or should I wait? Kind regards,

Robert Floor

[Stereo]

Hi Robert,

For now you can grab a working Java 14 build from ​https://github.com/thomersch/josm/suites/1032124261/artifacts/13674747

No Java installation required; it comes with batteries included.

[Robert Floor]

Thank you very much for the file, Would it also be possible to include javaFX in the build for the mapillary plugin ?

[Stereo]

Unfortunately, javafx isn't supported by the java packaging tools we use. For now, you can disable it for mapillary in the preferences - it affects the date/time chooser.

[anderfo]

Still an issue in macOS Catalina 10.15.6 (19G2021) and josm-macosx-17013.
Stereo's link above to ​https://github.com/thomersch/josm/suites/1032124261/artifacts/13674747 is dead.

What's the recommended solution at the moment?

[Stereo]

There will "usually" be a recent build up at ​https://github.com/thomersch/josm/actions. If you click on the top "Java CI" item, there'll be "JOSM.app revision 17015" in the Artifact section.

When I have time, I'll set up a proper way of doing releases.

You can try the new pre-releases at ​https://github.com/thomersch/josm/releases

[Stereo]

The new builds at ​https://github.com/openstreetmap/josm/releases work with a built-in Java 15 OpenJDK JRE. The next 'tested' release will use those.
