Steps to reproduce:

I have tried to execute a simple app that launches VM in debug mode using LaunchingConnector and that sets several WatchPointRequests. When one of the correspondent WatchPointEvents should be generated the debugged VM crashes.

See attached files:
Run Operator class. It debugs VM running TestCase class.

Report generated by the crashed VM:
