Sergey Beryozkin commented on CXF-5689:
---------------------------------------
Do you mean that you have a custom ResponseExceptionMapper implementation and
you have Providers injected into it and call
providers.getContextResolver(aClazz, aMediaType);
from its fromResponse method ?
> 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: Hooman Valibeigi
>
> 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)
