["Sergey Beryozkin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CXF-5689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13969661#comment-13969661 ] 

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 ?

> 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)
