I am currently migrating an application from Karaf 3.0.8 to Karaf 4.2.1.
I have problems with a bundle, it can not instantiate a JAXB context object.
It throws the following exception:
java.lang.RuntimeException: Provider for class

The class org.apache.xerces.jaxp.SAXParserFactoryImpl comes from bundle
mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.xerces/2.12.0_1
it is provided by the wss4j from the cxf-3.2.7 feature.
When I add an import to org.apache.xerces.jaxp to the bundle then JAXB is
working. But this cannot be the solution because it binds my bundle onto
this implementation.
How can I solve this problem?
