While running PersistentColocatedPartitionedRegionDistributedTest a
thousand times to verify that I've fixed a flaky issue in the test, it hit
an interesting failure trying to send a RequestImageMessage. This generated
a stack trace which caused the test to fail grep for suspect strings. I can
easily suppress this failure, BUT it looks like a bug in message
distribution which may have been introduced by the recent membership
changes (modularization).
Here's the stack trace for anyone who wants it (I'm not working on this):
