[Nix-dev] openjdk cannot run GUI applications in NixOS

By the way: an interesting testcase is the Netbeans. I wrote the expression in such a way that it uses Oracle's JDK. If you replace it with OpenJDK, netbeans does not start and does not show anything.

I'm currently trying to invoke GWT stuff from a Maven script. The GWT tool is a GUI application and it tries to communicate with the X server, but it fails somehow. If I override the jdk in Maven to use Oracle's JDK, it works fine and it shows me the GWT Development Mode GUI.

Hi Sander,

I know that almost nobody uses Java GUI applications nowadays, but I have noticed that I cannot run AWT/Swing applications with OpenJDK (although the Oracle JDK works fine). For example, I cannot run netbeans with OpenJDK.


What error are you seeing?

I have circumvented the issue by utilising Oracle's JDK in the netbeans expression, but it would (of course) be much nicer to use OpenJDK.

I haven't packaged OpenJDK, but perhaps someone knows a solution for it.

Regards,

Sander
