We are experiencing Tomcat failure as soon as the following exception gets thrown;

This exception we have discovered mostly occurs after a developer compiles classes to
Tomcat which makes Tomcat restart the context. Mostly, because sometimes it is fine.
We cannot establish a concrete pattern of behaviour except that some compiles of any
class type that make TC reload the webapp cause this unercoverable error.
This has happened with log4j1.2.8 and 1.3alpha0
