And being unable to write whole compressed data on array, on s390 whole data can't be recovered after compression. So this fix increase Array size (for s390).

Hello Amit, I had a look at the latest state of this PR, commit `bce8989275`. 

What this change does is that it updates the `check` method in the `DeInflate` test to no longer rely on pre-defined lengths/sizes to determine whether deflate followed by an inflate of data worked correctly. These sizes can vary depending on the underlying `zlib` implementations. The updated `check` method now uses a `ByteArrayOutputStream` to deflate into and then inflate from. The final inflated data is then compared against the original input and asserted that it's the same (this part hasn't changed in this PR). These changes look fine to me.
