startClusterManagementService throws NPE
Anyone know why we keep intermittently dealing with this suspect string in
dunit tests?
I think we need all valid ways of starting up a Locator to be in a state
that NEVER produces this NPE. But I'm not sure how to fix it because I'm
not familiar with startClusterManagementService. Some pointers on how to
fix, please?

Is there a specific test that would cause this NPE? I will try to take a
look at it.

I think this may only occur in tests that perform a reconnect of the
Locator.
