Sure, I'll fix it.
By the way, Dan, how difficult would it be to enhance CXF for WSDLManager be loaded only when it is used. I recall you were doing
some work for 2.2.4 and I was able to verify that a number of dependencies for CXF-JAXRS case only dropped as a result, but wsdl4j
was still required, that is why cxf.xml was also modified, as reported in this thread...
cheers, Sergey

Hi
thanks for your post.
At the moment. the default providers are preinstantiated, the Aegis one you
registered will be chosen before the default one...
Ideally, the default providers would be created on teh demand but it would
introduce its own complexity (synchronization, etc)...
Not sure yet how to deal with this issue. Is it really the fact that JAXB
classes are referenced from the JAXB provider that causes this
SecurityException ?
Yea. That will definitely cause an issue on AppEngine. My suggestion would
be to change all the calls in setProviders(Object... providers) to be wrapped
with an exception catch that would log that it wasn't registered:
if (MessageBodyReader.class.isAssignableFrom(oClass)) {
try {
messageReaders.add(new
ProviderInfo<MessageBodyReader>((MessageBodyReader)o));
}catch (Throwable t) {
//could not register it
}
}
Also, change the calls in the static initializer to be more like the
JSONProvider which is then not loaded if the requirements for the
JSONProvider are not met.
Dan
thanks, Sergey
