> CompressorStreamFactory was immutable prior to 1.5; r1453945 broke immutability. It's
also no longer thread-safe because the field decompressConcatenated is not safely published.
> It would be possible to make it thread-safe by making the field volatile.
> It could be made conditionally immutable by using the same technique as suggested in
COMPRESS-302, in preparation for removing the method setDecompressConcatenated in a future
API-break release.
