https://github.com/apache/metron/pull/1015
Cache eviction is performed asynchronously by default using the FJP common
pool. For testing you can set `executor(Runnable::run)` and it will be on the
calling thread. The penalty is small so it’s sometimes used in practice anyway.
The eviction is not LRU and has a random seed to guard against HashDoS
attacks. This means that which entry is not predictable without forcing the
seed, which is not exposed. Typically only the cache’s test should do that.
You’re code shouldn’t make assumptions on what is evicted as we will try to
maximize the hit rate using various techniques.

Daft. Still a problem. In master, run repetitively the test fails easily
3/10 times for me. With the latest in this PR, it is failing 1/40 times or so,
so I'm still not there.
So even explicitly performing cache maintenance does not mean that the
cache size will always be exactly what we expect.
I am wondering if we even need such low level validation as what we have in
testWithFullCache() now.

https://github.com/apache/metron/pull/1015
> @mmiklavc: Can you call out the lines relevant to the fix for reviewers?
I provided some more color in the description this time. Also, copied
below.
> The core problem is that the test makes assumptions about the cache state
which are not always true. Specifically, even though the cache max size is 2,
the cache can exceed that size for short periods of time until cache
maintenance is performed.
> Since the cache can be larger than expected for brief periods of time,
the expectations of what is a hit or miss were incorrect. This is why the test
would fail intermittently.
> To address this, I rewrote the test so that the cache stats are validated
after each expression is run and I also perform cache maintenance between each
execution and validation of cache state.
> Without the additional logging, the ability to grab more detailed cache
stats, and breaking down that test case, I wouldn't have been able to uncover
the bug.
