             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.
