Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - JAX-RS * **************************************************************** * PROBLEM DESCRIPTION: A thread containing a null CCL(Context * * Classloader) used for JAXRS processing * * will result in a NullPointerException * * in the * * com.ibm.ws.jaxrs.JAXRSRuntimeDelegate * * class. * **************************************************************** * RECOMMENDATION: * **************************************************************** Normally, if an application needs to change the context classloader, or null it out for a thread they will save the current CCL and then re-set it when their operations have completed. If the CCL remains null and JAXRS processing is attempted a NullPointerException in JAXRSRuntimeDelegate will result. This is not a regression.
Problem conclusion
Adding the CWSRS1009W (nullContextClassloaderWarning) message to alert the user to this situation and provide information. The fix for this APAR is currently targeted for inclusion in fix pack 22.0.0.5.
