Launch instance wizard: cannot access webapp (404) if using ami-7ad22213

Despite the fixes in JBIDE-8261, multiple issues seem to persist with remote AS when using this setup.

First, it seems RSE loses the connection at a certain point (10 minutes? not sure), and all efforts to restore it are lost. This means that even efforts to upload new changes fails.

Second, even if i manually scp files (some new Dyn Web proj) to the server and then mv it into the deploy folder, they often are not recognized. In fact, it seems the entire deployment scanner shuts down and all efforts to restart it fail.

Even efforts to craft, on the machine in VI, a new -ds.xml file, and move it in, fails.

Even restarting the deployment scanner with the following commands fails:
/opt/jboss-as6/bin/twiddle.sh -s service:jmx:rmi:///jndi/rmi://EC2-184-72-200-3.COMPUTE-1.AMAZONAWS.COM:1090/jmxrmi -u admin -p admin invoke jboss.deployment:flavor=URL,type=DeploymentScanner stop

/opt/jboss-as6/bin/twiddle.sh -s service:jmx:rmi:///jndi/rmi://EC2-184-72-200-3.COMPUTE-1.AMAZONAWS.COM:1090/jmxrmi -u admin -p admin invoke jboss.deployment:flavor=URL,type=DeploymentScanner start

They do not fail with exceptions, and the twiddle finishes as expected.

So all in all, this is just extremely baffling. It has elements of RSE errors (losing connection), elements of AS6-errors (deployment scanner start / stop really not doing a damn thing), and I'm sure my tools are also not exempt from errors.

Unfortunately, code freeze is here and the best I can do is log errors.
