The class LoggerFactory is used by the bridging APIs for requesting a Logger instance of the SLF4J underlying implementation. The ContextSelector is only called in the constructor to retrieve an ILoggerFactory instance. The factory will then be used until the end of the application.

For a correct support of a ContextSelector implementation, LoggerFactory should use for each request the ContextSelector in order to retrievee an ILoggerFactory instance.

A quick fix is applied at this bugreport.
