[Tristan Yan]

Hi Joe, Alan and all others

Would you please help reviewing these tests? The intent is moving some JAXP tests from closed to open. The associated bug number is
https://bugs.openjdk.java.net/browse/JDK-8047962 <https://bugs.openjdk.java.net/browse/JDK-8047962>.

These tests have been ran with and without the Security Manager. All the tests pass under both scenarios.

Thank you.
