------------------------------------------------------------
I attached ManagementListenerDeadlockRegressionTest.java. The class requires PR
#3098 and PR #3099.
Download the file to
{{geode-core/src/integrationTest/java/org/apache/geode/management/internal/beans/ManagementListenerDeadlockRegressionTest.java}}
The test will confirm the existence of the deadlock on a Mac within about 30
seconds.

> The only combinations of code paths I can find that has the potential to hit
> this deadlock is:
> * Thread-1 is invoking Cache.close()
> * Thread-2 is invoking Region creation for a persistent Region that will use
> the default Disk Store which has not yet been created
> This is a product deadlock that was discovered by analyzing a dunit hang
> (GEODE-6232).
