Hi all,
I just run into a bug trying to generate a process image and I think this information can be useful to save some time if anyone have the same problem.
Here is the situation:
My environment:
Guvnor 5.5.0.Final
jBPM Designer 2.4.0.Final
OpenJDK 1.7.0_09-icedtea
EAP6
RHEL6.3
Basically if you try to export a process image you get a file not found as response. However, a process image file is created on Guvnor(0 bytes). Looking at the logs you will not see much information about the error.
After some investigation I could get the following stacktrace:
17:21:51,730 ERROR [stderr] (http-localhost/127.0.0.1:8080-23) java.lang.NullPointerException

It turns out that this problem is related to the following OpenJDK bug: http://bugs.sun.com/view_bug.do?bug_id=7068471 http://bugs.sun.com/view_bug.do?bug_id=7068471, which is fixed only for OpenJDK8.
To get around this problem I installed the following package dejavu-sans-fonts on RHEL6.
If you google for NullPointerException sun.awt.X11FontManager.getDefaultPlatformFont you can find many other people having similar problems.
Hope this information can be useful.
Happy process modeling! ;)
