Description

I noticed this by running out of space while working on CASSANDRA-18706. Something must be calling HeaupUtils.maybeCreateHeapDump because the build/test directory is littered with pidxxxx-epochxxxxxxxx.hprof files despite the tests not crashing. I checked a couple other random tests, RandomSchemaTest also generates a dump but KeywordSplitTest does not.

This behavior does not occur on 4.1.
