That is OK, i do no think such things are easy to find, quicker to ask
on the list :-)

Ah, that might be due to abstract bean definitions that i have fixed
in 1.0.2-SNAPSHOT:
- Fixed issue 191
https://jersey.dev.java.net/issues/show_bug.cgi?id=191
ResourceConfig.isProviderClass and
ResourceConfig.isRootResourceClass return
false if the class parameter is null.
This fixes an issue with the SpringComponentProviderFactory
throwing an NPE
for abstract Spring beans.
Is that the case?
If you need to work on a stable release, you could copy the 1.0.2
SNAPSHOT code for Spring and plug it in yourself.
