QPID-8398: [Broker-J][AMQP 0-9] Use SoftReferences to access decoded message
heades in order to GC them before running into OutOfMemory conditions
> [Broker-J] [AMQP 0-9] Improve heap usage utilization by small transient
> messages with headers

> Key: QPID-8398
> URL: https://issues.apache.org/jira/browse/QPID-8398
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-broker-7.1.0, qpid-java-broker-7.1.1,
> qpid-java-broker-7.1.2, qpid-java-broker-7.1.3, qpid-java-broker-7.1.4,
> qpid-java-broker-7.1.5, qpid-java-broker-7.1.6
> Reporter: Alex Rudyy
> Priority: Major
> Fix For: qpid-java-broker-8.0.0, qpid-java-broker-7.1.7
>
>
> The Qpid Broker can crash with OutOfMemoryError when small transient
> messages with decoded headers occupy the entire heap without triggering the
> flow to disk. The direct memory utilization by the messages is below the flow
> to disk threshold. As result, the decoded message headers are accumulated in
> heap and can cause OutOfMemoryError.
> The heap utilization can be improved by using {{SoftReferences}} for decoded
> headers. That should allow to GC the headers on running into heap OutOfMemory
> conditions
