ProM 6 UI freeze problem

thobai

Hi there,

for quite a while I'm experiencing problems with ProM 6 and my own package, Event2ActivityMatcher. The problem is that after starting ProM from within Eclipse, it already freezes when clicking the import button. Not always on the first attempt. Not always anyway. But quite often. When I do this in debug mode, I see the following when pausing the execution:

It seems that there is some deadlock in the UI where some component waits for something forever. I'm on Mac OS 10.9 using JDK1.7.0_60. Everything is set up to use and compile for JDK 1.7 (and I have a slight feeling that it has to do with that as I never experienced problems before, but some of the libraries I use depend on Java 1.7).

Does anybody have any suggestion on how to fix that?

Best,

Thomas

Could it be an Apple JDK related bug? (see https://netbeans.org/bugzilla/show_bug.cgi?id=212056)

Did you try the Oracle JVM and/or update the JVM?

Hey Joos,
Sorry for the very late reply. I do use the JVM provided by Oracle. Not the Apple JDK. Also tried Java 8. The problem also remains on OS X 10.10. Any ideas what to try next?

Cheers
