-------------------------------------

For me, this problem happens everytime I stop the JBoss server by right-clicking the server in the Server View and selecting Stop, which is not at all helpful for you.

I have stepped through the code to get a better understanding of what may be causing this problem, so maybe I can describe what I am seeing and it will help you to understand the cause.

Above I had mentioned that commenting out pollServer(IServerStatePoller.SERVER_DOWN); in the JBossServerBehavior.serverStopping() seemed to fix the problem.  I added back in this line of code so that I could locate the statement that causes the JBoss process to be blown away.  

The problem seems to start in the pollServer() method on the last statement, which is a call to pollThread.start().  This causes the PollThread.run() method to be executed.  The last statement in the run() method is a call to alertBehavior().  The code drops through to the last 'else' statement in alertBehavior(), which is a call to behavior.forceStop(false).  Executing this statement causes the JBoss process to be blown away.      

I appears that another process is started to execute the shutdown code.  What I am seeing is that the JBoss process is already gone by the time the shutdown attempts to stop JBoss.  This results in the error I mentioned above.

I am wondering why another PollThread is started in pollServer when the JBoss server is being shut down?  I made the following code change at the end of the pollServer() method that also seems to solve the problem I see:

    if ( expectedState != IServerStatePoller.SERVER_DOWN ) {
        this.pollThread = new PollThread("Server Poller", expectedState, this);
        pollThread.start();
    }

Hope that helps.

> When stopping JBoss from the Eclipse Server view, I receive the following error:  "Could not obtain connection to any of these urls: localhost:1099".  I found that this problem occurs because the process in which JBoss is running is terminated before shutdown is executed.  I found that eliminating the call to pollServer(IServerStatePoller.SERVER_DOWN); in the JBossServerBehavior.serverStopping() method resolves the problem, though I am not sure that this is the final fix.
