-----------------------------------

             Summary: Java Broker: default log4j configuration outputs line numbers, which is a performance drag
                 Key: QPID-4517
                 URL: https://issues.apache.org/jira/browse/QPID-4517
             Project: Qpid
          Issue Type: Improvement
          Components: Java Broker
    Affects Versions: 0.20
            Reporter: Philip Harvey
            Assignee: Philip Harvey
            Priority: Minor


By default we produce this sort of logging:

{noformat}
2012-12-20 09:52:51,490 INFO  [main] (AbstractConfiguration.java:124) - Tag:'path'
{noformat}

Including line numbers is slow, as described by the log4j documentation (http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html):

"WARNING Generating caller location information is extremely slow and should be avoided unless execution speed is not an issue."
