Gary Tully created AMQ-7035:
-------------------------------
Summary: Memory usage incorrectly increases when selectors are
used in JMX operations
Key: AMQ-7035
URL: https://issues.apache.org/jira/browse/AMQ-7035
Project: ActiveMQ
Issue Type: Bug
Components: JMX
Affects Versions: 5.15.0
Reporter: Gary Tully
Assignee: Gary Tully
Fix For: 5.16.0
The default MessageEvaluationContext does referencing counting and requires a
usage pattern that ends in a call to clear(), this pattern has not been applied
in a few places in error. The fix for AMQ-6465 works around the non use of the
pattern.
The JMX operations that use a selector do not use that pattern and hence can
leak a reference count.
The NonCachedMessageEvaluation context does away with the reference count and
this is used in most places. I think it should be used everywhere, the whole
selector cache idea never got completed.
