Re: [p2-dev] P2 planner test testSubsequentInstall in AgentPlanTestInRun

This code has not changed since M7 and we have been having clean builds for weeks.
I'm wondering if you are not getting burnt by running the tests in the UI. Try running the tests using the "[no application]" application.
Btw, are you running the tests from source?

After Updating to the new Eclipse 3.5 RC3 the freezing has upgraded to a Null Pointer Exception.

In AgentPlanTestInRunningInstance lines 69:70:71
{
It seems that when the rollback plan is devised by getting the Diff of the initialProfile
It tries to remove the Engine Bundle For some reason , this causes the EngineActivator to stop and its context to be set to null.
}

This context is used when trying to get the Service in the Engine class, on line 40
SimpleProfileRegistry profileRegistry = (SimpleProfileRegistry) ServiceHelper.getService(EngineActivator.getContext(), IProfileRegistry.class.getName());


Here is the Stack where the EngineActivator is stopped and the Context set to null
