Subject [jira] [Created] (QPID-7911) TopicExchange leaks per topic name
Date Tue, 12 Sep 2017 12:09:01 GMT
Keith Wall created QPID-7911:
--------------------------------

             Summary: TopicExchange leaks per topic name 
                 Key: QPID-7911
                 URL: https://issues.apache.org/jira/browse/QPID-7911
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
    Affects Versions: qpid-java-6.1.4
            Reporter: Keith Wall


The {{TopicExchange}} class (used by instances of the topic exchange, including {{amq.topic}})
leaks a TopicExchangeResult instance for each unique topic name (binding key).   For use-cases
involving perhaps short lived random generated topic names, this leak could lead to an {{OOM}}.

I have verified that the problem exists on 6.1.4.  I strongly suspect this defect would be
present in older version of the Java Broker too.
