Details

    Description

      When shutting down the server, this exception gets raised: 

      11:33:04,028 INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal
11:33:04,032 ERROR [org.jboss.ejb.client] (MSC service thread 1-3) EJBCLIENT000513: Exception occurred when trying to close the transport provider: java.lang.NullPointerException

      The ClientServiceHandle.close() method needs to use safeClose() in case the channel variable has not been initialized, which can happen if the service creation is cancelled or raises an exception.
