Branimir Lambov commented on CASSANDRA-11913:
---------------------------------------------
Thank for the patch. I would not change the array size to still catch the bug
of compressor using the size of the array instead of passed length. Fixing just
the {{arrayCopy}} should be enough to sort the problem.

> org.apache.cassandra.io.compress.CompressorTest causes
> java.nio.BufferUnderflowException on environments where FastByteOperations
