             Summary: NPE at ThreadLocalProviders.getContextResolver()
                 Key: CXF-5689
                 URL: https://issues.apache.org/jira/browse/CXF-5689
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.7.11
            Reporter: Isis


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(aClazz, 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)
