Background of the failure was that we were running with user 'mytestuser' . However a folder

C:\temp\hsperfdata_MYTESTUSER

existed on the system and this mismatch of mytestuser and MYTESTUSER caused the test (and jps) to fail.
We could look into adding logging that shows the issue, or make the folder handling more flexible in the JVM code.
