RFR: 8150145: javax/xml/jaxp/unittest/common/TransformationWarningsTest.java and ValidationWarningsTest.java failed intermittently without any error message

Hi Aleksej,

It's good to put the tests back online. Thanks for the diligent work! I 
believe the change that made the tests run in othervm could have fixed 
the intermittent issue. But adding debugging code can always be helpful 
in case of failures.

Thanks,
Joe
