some extra space here.

I've re-read the discussion and I don't think the real issue is clear at this time. Can you check if it only needs additional space for the DEFAULT_COMPRESSION level, maybe change the loop to only test levels 0-9 and see if it passes?

On determinism, then the test fills dataIn will random byte values, and the input length will be some random length up to dataIn.length, but otherwise I don't see anything that should cause the failure you are seeing.
