This problem applies to NetBeans 7.0 as well. xprop shows these properties for the NetBeans window:
WM_CLASS(STRING) = "sun-awt-X11-XFramePeer", "java-lang-Thread" However, using StartupWMClass=sun-awt-X11-XFramePeer or StartupWMClass =java-lang-Thread in a .desktop file does not help the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757991 Title: java applications a double icon appears -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
