CLONE [JBREM-944] - Fix race in ConnectionNotifier -------------------------------------------------- Key: JBREM-974 URL: http://jira.jboss.com/jira/browse/JBREM-974 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 2.4.0.CR2 Reporter: Ron Sigal Assigned To: Ron Sigal Priority: Minor Fix For: 2.4.0.GA org.jboss.remoting.ConnectionNotifier.connectionTerminated() throws NullPointerExceptions from the following code: ConnectionListener[] list = (ConnectionListener[])listeners.toArray(new ConnectionListener[listeners.size()]); for(int x = 0; x < list.length; x++) { list[x].handleConnectionException(ex, client); // <<== NPE's thrown here } It seems that listeners got smaller between the call to listeners.size() and the call to listeners.toArray(), which could result in list having one or more null elements.
