PI75593: SUPPORT THIRD-PARTY JAX-RS PROVIDERS WHEN JAXRS-1.1 FEATURE IS CONFIGURED

Fixes are available

APAR status

Closed as program error.

Error description

If you put Jersey in your application and configure jaxrs-1.1
you get this exception:
java.lang.NullPointerException at
org.apache.wink.common.internal.http.
Accept.valueOf(Accept.java:139)

This is because the Jersey RuntimeDelegate implementation is
registered, but we try to go through the wink dispatching
servlet for REST. Also the Jersey RuntimeDelegate is registered
for the whole JVM rather than specifically for the app so
putting Jersey in one app interferes with other apps.

Same occurs under Liberty see PI27070 for details in that
environment.

Local fix

```
Remove Jackson/Jersey from the server
```

Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server            *
*                  users using jaxrs-1.1 and a third           *
*                  party JAX-RS provider                       *
****************************************************************
* PROBLEM DESCRIPTION: NullPointerException occurs when using  *
*                      third-party JAX-RS provider with        *
*                      WebSphere Application Server jaxrs-1.1  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The jaxrs-1.1 packaged with the WebSphere Application Server
incorrectly intercepts REST requests for  all applications,
even ones that contain their own JAX-RS provider. It then
incorrectly attempts to integrate with the application's
JAX-RS provider, causing the exception.

Problem conclusion

The jaxrs-1.1 code has been updated to detect when a third-
party JAX-RS provider exists in the application and ensures
that it does not get invoked as a result of the REST request,
instead allowing the third-party JAX-RS provider to invoke the
application.
The fix for this APAR is currently targeted for inclusion
in fix packs 8.5.5.12 and 9.0.0.4. Please refer to the
Recommended Updates page for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980

Temporary fix

Ensure that the application using the third party JAX-RS
provider contains both the JAX-RS implementation and JAX-RS
API jars and that the META-INF/services within the application
are properly configured to use the 3rd party's RuntimeDelegate.
