No, I don't see any similar traces in bugzilla. Please log a bug report
with Platform - SWT and include the full stack trace and if possible a
stand-alone snippet that reproduces the problem for you.

Thanks,

Not being an expert on the inner workings of SWT on win32, I'm not going to push my opinion as cannon. However, it looks like this is a threading issue. Is it possible that SWT isn't ensuring that the event is being passed to the win32 subsystem in the event dispatch thread?

After some researches, here is the problem...

1) my applications jar files is on the network(also the swt.jar)
2) i'm launching the application from my workstation 'java.exe -cp blabla'
3) the network shuts down
4) i continue the navigation into my application (click button, open tabs,
...)
5) the network is available
6) hs_err_pid created in the application folder(on the network)
