[jboss-jira] [JBoss JIRA] Updated: (JBREM-654) a NullPointerException occures and is not handled in SocketServerInvoker and MultiplexServerInvoker

[Claudia Richter (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBREM-654?page=all ]

Claudia Richter updated JBREM-654:
----------------------------------

    Attachment: SocketServerInvoker.java

I guess I found the solution. The NullPointerException was thrown when the ServerSocketRefresh Thread did set socketServer to null, but the closing of socketServer was not finished. So the main Thread still ran the socketServer.accept() method. a simple flag which is set, when the accept method throws a SocketException solved the problem. I did attach the SocketServerInvoker class, in which the flag is used.

> when trying to dynamically load keystores several times, it happens that the SocketServer is set to null and a NullPointerException is thrown. MultiplexServerInvoker and SocketServerInvoker are both not able to handle this Exception. Actually no NullPointerException should be thrown, but it happens. This Exception causes the Server to fail.
