If you are attempting to take advantage of the feature of the Application Bridge that enables it to increment to the next available port (you selected a range of ports for a Remote Application type of remote session and used the <$HOSTS> variable to load the local IP address), and it does not increment, you need to clear the Java Plug-in cache. The cache is storing an earlier version of the AppBridge.jar file. This feature is available as of the Summer '11 Release, Summer '11, Upgrade 2, release.
