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: 2.2.2.SP12, 2.5.0.SP3 (Flounder)
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().
