Hi,

We have JAXB classloading issues in the OSGI using CXF 2.2.10 in Fuse 4.3-02  . It looks like when different JaxbContexts tries to load the same Jaxb class binding that has been load before throws this exception. So we got this exception for every single request :

Is this a JAXB/OSGI issue or it is related to CXF ?

Thanks,
