I confirm that switching to openjdk 7 instead of openjdk6 solves the issue on my computer :
sudo apt-get install openjdk-7-jdk icedtea-7-plugin sudo update-java-alternatives -s java-1.7.0-openjdk That's good news. Unfortunately, openjdk-6 is still the default JVM on Ubuntu 12.04 (see packages default-jdk and default-jre) Shouldn't the fix be backported to openjdk 6, so that all the Swing applications appear correctly by default on Ubuntu 12.04? I suppose the status for openjdk-7 should be changed as "fix released"? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/932274 Title: Regression: Unreadable menu bar with Ambiance theme in Java/Swing GTK L&F To manage notifications about this bug go to: https://bugs.launchpad.net/light-themes/+bug/932274/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
