Notes client with embedded sametime 9 crashes when launched from eclipse

I often start my Notes client from eclipse to debug our plugins in the client. I have described how to configure eclipse to start notes from eclipse in an older blog post. Yesterday our Admin has installed the sametime 9.0 embedded client in my Notes installation and after that Notes crashes when started from eclipse with the following error in the error log:

I have tried to reload the target platform and activated all plugins in my launch configuration, but with no success. The client still crashes after my user is logged in the sametime community. So i have dug deeper and found out that you have to set some jvm parameters to prevent the crash.

The parameters are:

-Xjit:noResumableTrapHandler
-Xmaxt0.6
-Xmca8k
-Xminf0.1
-Xmn7m
-Xms48m
-Xmx1024m


and should be added to your launch configuration.

Settings to prevent IBM Notes Sametime Crash

  1. We have a PMR for this problem right now, and IBM has so far indicated that there might be a problem with the Sametime client. We received a hotfix which has run successfully so far. So, expect a fix in the (hopefully near) future too.
