[Pkg-osm-maint] Bug#718803: josm only shows blank main window after start with OpenJDK 7

[Roland Hieber]

Package: josm
Version: 0.0.svn5759+dfsg1-1
Severity: important

Dear Maintainer,

after a system upgrade to OpenJDK 7u21, I started josm again. The splash screen
appeared, and after that, I got nothing but a gray window as the josm main
window. It is however possible to close it by pressing Ctrl-Q, so I guess it
works but only the paint is missing.

Output on terminal is the following:

rohieb at r2d2:~$ josm
Using /usr/lib/jvm/java-7-openjdk-amd64/bin/java to execute josm.
Picked up _JAVA_OPTIONS: 
Look and Feel not found: javax.swing.plaf.gtk.GTKLookAndFeel
Enabled EDT checker, wrongful access to gui from non EDT thread will be printed to console
rohieb at r2d2:~$

When using OpenJDK 6u27 through update-alternatives, everything is back to
normal (even with GTK look and feel).
