[jboss-remoting-issues] [JBoss JIRA] Closed: (JBREM-1081) Fix NPE in ServerInvokerCallbackHandler

Fix NPE in ServerInvokerCallbackHandler ---------------------------------------- Key: JBREM-1081 URL: https://jira.jboss.org/jira/browse/JBREM-1081 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 2.5.0.SP2 (Flounder) , 2.2.2.SP11 Reporter: Ron Sigal Assignee: Ron Sigal Priority: Minor Fix For: 2.5.0.SP3 (Flounder), 2.2.2.SP12 When org.jboss.remoting.callback.ServerInvokerCallback is shut down by a call to ServerInvokerCallbackHandler.destroy(), the variables callBackClient and callbackStore are set to null. If ServerInvokerCallbackHandler.handleCallback() is called subsequently (which can happen if destroy() is called by ServerInvokerCallbackHandler.handleConnectionException() and the application has not yet been informed about a connection failure), then, since callbackClient == null, it looks like pull callbacks are configured, but, since callbackStore == null, a NullPointerException is thrown in ServerInvokerCallbackHandler.persistCallback().
