Error description
The absence of a WLM Enclave on the thread In Liberty support of Async Servlets using the servlet-3.1 feature should not create an FFDC entry. Based on httpClassifcation definition that may be what the customer has intended the server to do.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty for z/OS * **************************************************************** * PROBLEM DESCRIPTION: FFDC may be received for WLM * * unclassified request using Async * * Servlet support * **************************************************************** * RECOMMENDATION: * **************************************************************** An FFDC is produced in the Async Servlet WLM Context management path if there is currently not a WLM enclave of the thread. This will occur normally if the WLM Classification rules determined that the current request is not classified (ie. no WLM Enclave is created). This can occur with the combination of the servlet-3.1 and zosWlm-1.0 features. The following is more detail of the FFDC produced: Exception = java.lang.IllegalStateException Source = com.ibm.ws.zos.wlm.context.servlet.async.internal.WLMTransferCon textServiceImpl probeid = 188 Stack Dump = java.lang.IllegalStateException: An enclave was not found on the current thread. Unable to save enclave state information for asynchronous processing tracking.

Problem conclusion
Code has been modified to not issue an FFDC if a request is not classified with the WLM classification rules. The fix for this APAR is currently targeted for inclusion in fix pack 17.0.0.4.
