With passing CI.

The CI is passing including the tests on windows but at the end in the test-result section I see this error

Can I consider this as CI green ? @dirk-thomas

@brawner maybe you want to have a look on this error:

We had set windows workers to use a larger heap space, awhile ago but it appears it hadn't actually made it into the AMI, so these workers were setting too small of heap space for the jenkins agent. This has nothing to do with the build itself and is something that we're working to resolve. Sorry for the trouble

Yes, worst case we miss some warnings which we can follow up on afterwards 👍
