Description Frederic Fusier

Verifying results for build I20090331-0901, I see one failure in Platform/Ant performance tests:

testBuildWithLotsOfLinks	Failure	Program did not suspend, launch terminated.

junit.framework.AssertionFailedError: Program did not suspend, launch terminated.

Note that this failure does not occur on Windows machine, only on Linux ones...

The normal test suite also had a failure (I20090401-1325) for a different test but the same symptoms - testRunToLineSkipBreakpointSepVM:

Program did not suspend, launch terminated.

junit.framework.AssertionFailedError: Program did not suspend, launch terminated.

I cannot see the failure in the I20090410-0800 perf results page. Coudl you confirm that this bug has been fixed? TIA

We have had very limited success reproducing the bug locally. It appears to be a timing issue - we wait for a suspend event that sometimes seems to never come.

This is a transient failure that has happened historically in some debug tests. Unless the problem persists reliably, I suggest to mark this one as works for me.

Verified for RC1 with I20090430-2300 (aka M7) results

Sorry, should read: Verified for M7...
