[jira] [Created] (QPID-6800) Use cached direct buffers for message compression/decompression

Keith Wall created QPID-6800:
--------------------------------

             Summary: Use cached direct buffers for message compression/decompression
                 Key: QPID-6800
                 URL: https://issues.apache.org/jira/browse/QPID-6800
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall
             Fix For: qpid-java-6.0


Currently when the 0-8..0-91 and 0-10 protocol engines compress/decompress message payloads on behalf of consumers, (non-cached) direct memory is allocated for the modified content and then shortly after released.  This approach is risky as the JVM may do release this memory in a timely manner and an OutOfMemoryError direct may occur.

Switch the protocol engines to use cached direct memory for compressing/decompressing message payloads.
