Description

I have extensions of the following classes in my application used as providers when creating jaxrs clients or servers.

javax.ws.rs.ext.ContextResolver
javax.ws.rs.ext.MessageBodyReader
javax.ws.rs.ext.MessageBodyWriter
javax.ws.rs.ext.ExceptionMapper
org.apache.cxf.jaxrs.client.ResponseExceptionMapper

All my custom providers have the following member field injected at runtime.
@Context private Providers providers;

Within the providers' methods I'm calling this:
providers.getContextResolver(aClass, aMediaType);

This is causing a NullPointerException for the ResponseExceptionMapper. All the other providers have no problem getting the context resolver.

java.lang.NullPointerException
at org.apache.cxf.jaxrs.impl.tl.ThreadLocalProviders.getContextResolver(ThreadLocalProviders.java:50)
