Whenever I attempt to add MappingJacksonHttpMessageConverter to my bean config I get a null pointer at startup and a dump. Strangely the app still works, but want to stop the dumping. Remove the Converter I don't get the dump.

I think it might relate to some reentrant issues. Has anyone danced with something like this? I've tried different version of the InstrumentableClassLoader, AspectJ libs, and JacksonConverter. Welcome random guesses, I'm not sure where to go from here.


Here is the mega stack trace:
