Description

Running WikiEngine.shutdown() too fast after WikiEngine initialization causes it to hang. Sample code.

        WikiEngine engine = null;
        try
        {
            engine = WikiEngine.getInstance( new MockServletContext("JSPWiki"), props );
        }
        catch( Exception e )
        {
            System.err.println("Error starting JSPWiki: "+e.getMessage());
            e.printStackTrace( System.err );
            System.exit(5);
        }

//        Thread.sleep(10);
        
        try
        {
            ContentManager mgr = engine.getContentManager();
        }
        finally
        {
            engine.shutdown();
        }
        

Depending on whether the Thread.sleep() is commented in or out this hangs or passes. My guess is that it's a race condition with some of the Threads that we start.
