Ok, I solved this myself. For anyone else who may run into this, it
appears in 1.0.1 the jersey-spring implementation changed to use only
Spring IoC for resolving providers, whereas in 1.0 just having @Provider
was sufficient. I annotated my ExceptionMapper with Springs @Component and
it worked fine.
