[jira] [Created] (LOG4NET-512) Thread safety issue in Hierarchy.cs

Joe created LOG4NET-512:
---------------------------

             Summary: Thread safety issue in Hierarchy.cs
                 Key: LOG4NET-512
                 URL: https://issues.apache.org/jira/browse/LOG4NET-512
             Project: Log4net
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.2.15
            Reporter: Joe
            Priority: Minor


>From inspecting the source code I believe there is a threading bug in the Hierarchy class.  Both of the methods Exists and GetCurrentLoggers access the internal hashtable m_ht without locking.

Impact is minor as both these methods are probably rarely called by third party code, and since they do not modify state, the worst that can happen is an unexpected exception.
