JavaFX calls unknown class

[taylor.smock]

What steps will reproduce the problem?

1. Install a Mapillary plugin snapshot (I used the version from ​https://gitlab.com/gokaart/josm-mapillary-plugin/-/jobs/500339283 -- download job artifacts, open zip, go to build/dist and copy the jar file to the JOSM plugins directory)
2. Install the appropriate javafx plugin (crashes on Windows and Mac, Linux not yet tested)
3. Restart, if necessary. I've only been able to reproduce using OpenWebStart (I haven't tested IcedTea yet). Calling the .jar file from the CLI with java -jar works (java -version indicates AdoptOpenJDK 11.0.6, in this case).
4. Download an area
5. If not already shown, show the Mapillary Filter toggle dialog (it uses JavaFX for date pickers)

What is the expected result?

No crash. :)

What happens instead?

Crash. :(

Please provide any additional information below. Attach a screenshot if possible.

Occurs with 11.0.6 Zulu Community Edition and 11.0.6 AdoptOpenJDK.

Problem with the automatic installation:

When updating to the lastest JOSM, it complained about the missing javafx for mapillary, and I chose "download and restart". However it did not download the plugin, nothing in the log, and after the automatic restart the problem remained. No loading of this plugin during restart.

I went to plugins were java-fx was still unticked, so I added it manually, which succeeded, the log said: "The following plugin has been downloaded <strong>successfully ... javafx-osx (35375)", now restarting: "INFO: loading plugin 'javafx-osx' (version 35375)". First test, mapillary seems to work.

@Polarbear-j: I should probably look into adding some kind of dialog for "virtual" plugins (i.e., if only one plugin matches, then offer to install that plugin. Otherwise, have a drop-down dialog to select a plugin.)

I don't know how much work that is going to be, and it would be in JOSM core (so earliest stable would be the June release, assuming I get the time to work on it).

Also, you should have opened a new bug for that, instead of posting in a (largely) unrelated bug.

Well, I think I found the root cause:
​https://github.com/openjdk/jfx/blob/jfx14/doc-files/release-notes-11.md#swing-interop-fails-when-run-with-a-security-manager-with-standalone-sdk

There might be a workaround somewhere, but I haven't found one that works on my system.
