I would expect them to fail more frequently, if this is really an issue?
It didn't happen on the daily eval runs and it didn't happen on any of our
GitHub actions builds.
I am also wondering if we could just fix the test (instead of switching the
data structure, which might impact memory consumption/ perf).

> Two tests

> `opennlp.tools.dictionary.DictionaryAsSetCaseInsensitiveTest.testEqualsDifferentCase`
> uses HashSet for entrySet while initializing the 'Dictionary' and thus the
