> The ByteArrayWrapperSerializerTest can consume up to 1gb of heap space on it's own.
> This is due to the parallelization in SerializerTestBase#testDuplicate running tests 10x in parallel, the test data being duplicate twice, the test using 32mb arrays and the duplication being run multiple times in a loop.
