Since upgrading yesterday to Apple JDK 1.6.0_51 on Mac OS X Mountain
Lion, a rather large application I wrote (around 100K lines of code),
which runs from the console ("java -jar xxx.jar", not from within an
".app" folder with a ".plist") and embeds a Jetty HTTP server, has
suddenly started triggering a Dock icon appearing, which is a bit
I've seen webapps in the past that do this, but that's undoubtedly due
to the way in which such webapps get Java2D contexts for drawing.
None of that is happening here.
There's been no changes to the code, and indeed it doesn't do this
with the latest Oracle JDK.
Is this a bug or something I can work around? Is it related to any
internal security fixes (something preparing a dialog, just in case)?
For info, both JDKs:
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
