build problem: test errors on windows

[Hubert, Eric]

Hi all,
 
trying to build synapse 1.2 branch including execution of unit tests I receive 
the following errors:
 
Tests in error: 
  testThreadSafety(org.apache.synapse.mediators.bsf.ScriptMediatorTest)
  testThreadSafety(org.apache.synapse.mediators.bsf.ScriptMediatorTest)
  [...]
  testThreadSafety(org.apache.synapse.mediators.bsf.ScriptMediatorTest)
 
Tests run: 124, Failures: 0, Errors: 55, Skipped: 0
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
 
Any idea?
 
Regards,
   Eric
