Description Bryan Hunt

2010-06-10 15:57:33 EDT

I have a reproducible core dump on Linux GTK.  The core dump occurs after I have called TableViewer.setInput().  The details to reproduce contain confidential information.  I will open an internal defect with the details.

Here is a portion of the dump:

Can you add a snippet so I can reproduce the problem on my machine ?

Can you tried with a different VM ?

Note, it looks like you are returning to the VM with a unhandled exception. Can you debug your code catching all expections and check that the code does not return from a callback with a expection ? For example, a runtime exception happens on mouse down and returns to the VM without being handled.

Felipe,

Check your internal bugzilla 129694 for instructions on how to reproduce the problem.  I'll try wrapping the code in a try/catch later today.  I don't think I can try another VM - I recall there being legal issues.

I had the chance to test the code on my Mac and instead of crashing, it showed me that my label provider was throwing a ClassCastException.  I fixed the problem in my code, and now the Linux client no longer crashes.

Silenio, isn't there a bug for this problem already ? (see comment 1)
