APAR status
Closed as program error.
Error description
Property com.ibm.ws.runtime.dumpShutdown=true is set to as outlined in article: Process to get a thread dump or javacore during server shutdown https://www-01.ibm.com/support/docview.wss?uid=swg21304559 During shutdown it is generating two heapdumps and two javacores during shutdown. This looks like the shutdown process is executing the server's shutdown hook twice. The error does not actually cause any functional problems in the server, and the second javacore can simply be ignored.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Shutdown diagnostics produce double * * javacores during normal server * * shutdown * **************************************************************** * RECOMMENDATION: * **************************************************************** The com.ibm.ws.runtime.dumpShutdown system property configures the server to create extra diagnostic output during its shutdown process, including call stacks and javacores (or thread dumps). Because the code creating the javacore lies within a method that's called twice in typical stop scenarios, enabling this option will often lead to a second javacore when only one should be expected.
Problem conclusion
Additional checking was added during shutdown to avoid creating the duplicate javacore. The fix for this APAR is currently targeted for inclusion in fix packs 8.5.5.17 and 9.0.5.2.
