Method JDO_Test.tearDown catches any exception thrown during cleanup and turns it into a failure. So the stacktrace as shown in the description does not indicate the place where the NullPointerException is thrown. This will be improved as part of the fix of issue JDO-48.

Here is the stacktrace of the NullPointerException:
java.lang.NullPointerException
  at org.jpox.AbstractPersistenceManagerFactory.close(AbstractPersistenceManagerFactory.java:663)
  at org.apache.jdo.tck.JDO_Test.closePMF(JDO_Test.java:240)
  at org.apache.jdo.tck.JDO_Test.tearDown(JDO_Test.java:163)

This issue covers two problems:

- A global clean up strategy for all tests.
- PMF.close was called twice.

The first problem was fixed by JDO-48.
The second problem was fixed by JDO-58.

Reopened to set the Fix Version/s field to JDO 2 beta.
