[jira] [Created] (AMQ-7017) ProducerBrokerExchange.getPercentageBlocked() throws ArithmeticException (divide by zero)

Matthew Stratton created AMQ-7017:
-------------------------------------

             Summary: ProducerBrokerExchange.getPercentageBlocked() throws ArithmeticException (divide by zero)
                 Key: AMQ-7017
                 URL: https://issues.apache.org/jira/browse/AMQ-7017
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.15.4
            Reporter: Matthew Stratton
         Attachments: fix-producer-exchange-divide-by-zero.txt

I found this when testing a broker plugin for tracking messages sent (including some stats like getPercentageBlocked). When there have been no blocked messages an ArithmeticException is thrown due to an unchecked divide by zero. 

I fixed it and added a couple unit tests.
