> 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.
