issue with application finding tomcat jars

[Jason Ricles <jg...@alum.lehigh.edu>]

I have an application that uses the websocket jars from tomcat and
sometimes get this error,

java.util.ServiceConfigurationError:
javax.websocket.ContainerProvider: Provider
org.apache.tomcat.websocket.WsContainerProvider not found

Then it gets the error for a while and magically finds the jars and
runs which is weird. What may be causing this behavior to not find the
jars then magically find the jars?

Duplicate classes?  Note that the order of jars in WEB-INF/lib is
arbitrary and may change between runs.

Different Thread classloaders (Thread.getContextClassLoader()) ?

What is the full stacktrace of that error?
