Resolution: Fixed
> [Java Broker] [AMQP0-10] References to messages sent by $virtualhostProperties node retained by store

> Key: QPID-7958
> URL: https://issues.apache.org/jira/browse/QPID-7958
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-broker-7.0.0
> Reporter: Keith Wall
> Priority: Critical
> Fix For: qpid-java-broker-7.0.0
>

> On the 0-10 path, I notice that references to messages created by the {{${virtualhostProperties\}}} node are being retained internally within the store. This is leaking approximately ~1024 bytes per connection. Restarting the Broker or recycling the virtualhost frees the memory.
> The reference are being retained by the {{AbstractXXXMessageStore#_messages}} set.
> QPID-7783 added the _messages data structure. -It was back ported to 6.0 and 6.1, so the leak might be present there too. I have not verified this-. (updated 2017/10/06 does not affect 6.1 or 6.0. The MessageInstanceConsumerPair, which is no longer on master, unconditionally took a reference, so a reference was already taken).
