----------------------------------------
Github user nickwallen commented on the issue:
https://github.com/apache/metron/pull/1015
In the latest, I removed the problematic test case. There is no need to
test the eviction policy of the underlying cache, which is effectively what is
happening. If anyone can find gaps in test coverage, please let me know.
