Description

The endorsed java.lang.Exception, which expose the public method

public Class[] getClassContext() {
    return classContext;
}

is the reason of the failure of JaxB marshalling in certain use-cases (for example, when it is used for SOAP Fault by CXF). This is due to the method being seen as property (the method signature has the form of a "getter") and the default behavior of JaxB is to marshal properties.

As a result, any exception marshalled inside Karaf create an invalid XML which includes a list of <classContext> tags corresponding to this property, and clients outside of Karaf fail to unmarshall it.

The issue has been discussed on the Karaf Dev mailing list, see full discussion here:
