> - several occurrences of `ht.checkHashes("j2", Set.of("j3"));` (in jdk) not matching up with `ht.checkHashes("j2", "j3");` in jdk11u. I left the `checkHashes` function as it was simply removed the `ht.` to match the patch.
> - [`testHashModulesPattern`](https://github.com/openjdk/jdk/commit/e90388bc1e7bba92675fa799d9da77aa4d6e1a05#diff-90d72039e87e2a26eb11bd8e15e499aa96eef5372361fb1a47eec0d5ab168f5aR322) does not exist in jdk11u so I removed it from the patch.
