I'm wondering, is the problem here to do with the fact that DOSGI is trying to use the BundelContext/Bundle of the application
bundle to load the providers ? It should work if the providers's code is indeed inside a given app bundle but looks like it causes
issues if the provider's code is actually located elsewhere.
That said, if you own bundle imports the org.apache.cxf.jaxrs.provider.* then surely the OSGI loader has to be capable to find the
classes available elsewhere in the container, especially given that CXF minimal bundle is exporting org.apache.cxf.jaxrs.provider ?
Can you please check that your own bundle Import-Packag(es) the
org.apache.cxf.jaxrs.provider.* ?
thanks, Sergey

Maybe the full debugging output including stack trace can help more:

It's Felix over Pax Runner in my case. If I take the "sun.*,com.sun.*,javax.xml.bind,javax.xml.bind.*" packages out of the
bootdelegation classpath the following errors will occur:
java.lang.ClassNotFoundException:
org.apache.cxf.jaxrs.provider.JAXBElementProvider
java.lang.ClassNotFoundException: org.apache.cxf.jaxrs.provider.JSONProvider
For me, currently that doesn't make sense since the DOSGI bundle is fully resolved and all classes should be loadable. I'll
further investigate this...

S.B : Is it a single bundle distro ? Yes, it ships the stax api bundle I think...Hmm...Will it work if you try the multibundle
distro and omit the stax-api bundle ? Or perhaps updating the Equinox config to block the stax api from the system ?
