Date Wed, 30 Jan 2008 12:39:35 GMT
deadlock on re-registration of logger
-------------------------------------

                 Key: LOGGING-119
                 URL: https://issues.apache.org/jira/browse/LOGGING-119
             Project: Commons Logging
          Issue Type: Bug
    Affects Versions: 1.1.1
         Environment: Java 1.5, Windows
            Reporter: Nitzan Niv


Reached a deadlock inside common-logging while concurrently re-deploying 2 WARs.
In each WAR there is an attempt to get a logger:

private final Log logger = LogFactory.getLog(ContextLoader.class);
