unity launcher doesn't show starter correctly until restart

[Björn Kautler]

I'm having a problem. I distribute a Java application. jEdit to be precise. The application also provides a .desktop file in /usr/share/applications/. Directly after installing the .deb package, the Dash can find the application, but if I start it, only a gray box with question mark and title "win0" appears in the launcher. Pinning that is not possible, or rather it is possible but non-functional and also vanishes if you restart unity. This behaviour exists until Unity is restarted. From then on all behaves well. If I replace OpenJDK by Sun JDK everything works right from the beginning, so I think this is an issue with OpenJDK.
