Logger.getLogger(name, null) should not allow to reset a non-null resource bundle

Below shows the test case that passes with JDK 7 but fails with JDK8.

If a logger of a given name exists, Logger.getLogger(name, null) throws IAE when running with JDK 7. Looks like this is related to the fix for JDK-7045594 in JDK 8 [1].
