unity-window-decorator crashes when running a Java app

[Óscar Frías]

Binary package hint: compiz

When running a Java application (IntelliJ IDEA 9.0.4) under Ubuntu 11.04 I get an error when the application tries to open a popup. After the error all the windows lose their top bar.
This application was running smoothly under Ubuntu 10.10.

Same application running under unity-2d works without any problem.

[Lucas Madar (lucas-madar)]

I am having this same problem with another Java application. This makes natty unusable. Two of my other coworkers are having a similar problem.

Hi, same here. Several Java Dialogs Crash the unity-windows-decoration process.

[Leonardo Montecchi (lmontecchi)]

I'm affected by the same problem too, two java applications that I used in 10.10 without problems now crash when desktop effects are active. I have tried both with java-6-sun and with java-6-openjdk, with the same results.
Both the applications work correctly when using a "safe-mode" session

[Markus Pallo (pallo)]

same problem ubuntu 11.04 java app crash decorator

[Artem Medeu (artem-medeu)]

Same with Oracle Sql Developer and Netbeans. Window decorator crashes when program tries to open message popup window.
Eclipse runs without any troubles.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
