["Branimir Lambov (JIRA)" <ji...@apache.org>]

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 uses PureJavaOperations. The root cause is that CompressorTest.testArrayUncompress() copies data from a ByteBuffer to a byte array beyond the limit of the ByteBuffer.
