HttpSessionListener.sessionCreated() called twice for each session

On further experimentation, I noticed that this error only occurs when I define 
the tag library that contains the listener in the web.xml file with a taglib 
element. If I rely on auto-discovery of tag libraries, everything works fine.

Most likely, the listener is registered once when the container processes the 
TLD it finds through auto-discovery, and then again when it finds the TLD 
through the web.xml definition. Checking whether a TLD has already been 
processed before registering listeners should fix the problem.
