Screen Gray Out in Mac OS X 10.10 Yosemite Beta

[Aun Johnsen <lists@…>]

I am beta testing the next generation of Mac OS X, and have now a few times encountered a problem where the screen completely grays out (see attachment):

Without a deeper investigation this might be due to causes outside JOSM (problems in Java implementation, etc) but to capture your attention I report the problem here as well in the Mac Beta Feedback Reporting tool.

The times it have occurred with me have always been when opening the download dialog window. Both when no data have been loaded, and in the middle of edit sessions. It doesn't happen every time, this is about the 3rd occurrence in a week, and I am a heavy editor.

It doesn't seem like the download session has anything to do with it, as I use the continuous Download plugin with no problem.

It might be that a "refresh screen" type command in the download dialog, or something like that are acting strangely.

I never had this problem on OS X 10.9 Maverick, first time observed was first edit session in Yosemite.

Yes thanks. You can maybe give a try with java 8u20.

Do you think the problem is with Java 7?

[Don-vip]

It's clearly a problem between java and osx. Maybe java 8 has a different behaviour.

[Aun Johnsen <lists@…>]

I'm downloading the Java8 installer, but seems like this is still early development (no download from java.com/download for example), I will hold a little bit before actually installing Java8 to see what apple is responding to the feedback I sent through the feedback assistant, and to get a rough idea how often this occurs.

[Don-vip]

Java 8 is far stabler than your Beta Operating System ;) 8u20 is the first version we could qualify of mature, and the next update will probably be the default version on java.com, see ​https://blogs.oracle.com/henrik/entry/java_8_not_just_for. A lot of OS X bug have only been fixed in Java 8, that's why I asked you to give it a try. It won't break your machine.

[Aun Johnsen <lists@…>]

I will study this closer, there is a purpose for beta testing, and if it seems like OS X will move towards Java8 instead of Java7, than moving towards Java8 is sane in the beta testing, if they have any reason to continue using Java7, than I'll rather stay testing with Java7 (unless the problems make it too complicated for me)

[Don-vip]

Osx or apple has no word to say to java version since they finally agreed to let oracle lead java on their platform as it is the case on other systems. Believe me when I say that java 8 is globally better than java 7 for osx and that it will be soon the default version proposed by Oracle. Can you please give it a try, it's a matter of seconds. You can remove it after if you're really afraid.
