Hey just be glad we don't have a flat class path :)
Is there any reason why all three should not be imported by default? (I
am completely ignorant of JAX-RS so forgive me if that's a dumb question.)
They conflict with one another as JAX-RS binds marshallers based on
media type, target java class and target's annotations. Jettison and
Jackson have different default JAXB->JSON mappings and there's no way to
pick between the two without a special resteasy annotation. As for old
vs. new Jackson, there's no way to determine which one to use if no
Jackson annotations are being used. Its a cluster-bleep...
