QPID-7272 : Add a mechanism to dispose of byte buffers created by message conversion
> [Java Broker] Direct memory QpidByteBuffer created in message conversion modules should be disposed as soon as possible after becoming unused

> Key: QPID-7272
> URL: https://issues.apache.org/jira/browse/QPID-7272
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.0
> Reporter: Alex Rudyy
> Fix For: qpid-java-7.0.0
>
>
> Direct memory QpidByteBuffer in MessageConverter_to_1_0#convertServerMessage(...) is not disposed programmatically. We rely on GC to release it from memory when it became unused. There is a risk that when such QpidByteBuffers are not "garbage collected" soon enough Broker might run out of direct memory on heavy loads.
> Currently a user who relies heavily of message conversion with high rates of message flow, may see an OOM direct.
