I ran into a similar but possibly opposite problem on karaf trunk. For me,
when I deployed a jaxb 2.2/stax 1.2 + geronimo specs for these set of bundles
in karaf I got no contents to my top level jaxb object, but when I ran with the
jvm versions jaxb worked properly. At one point I got a setup where one of the
two elements inside my top level element was unmarshalled into a java object
and the other one wasn't.
I haven't figured out what is going on yet, but I do wonder with the
bootdelegation property set to include com.sun.* how any later sun jaxb
implementation can be installed as a bundle and work -- I'd expect all the
classes to be loaded from the vm no matter what you do.
I may well have to actually solve this problem soon so I'm very interested in
any clues about what is going on.
thanks
