Fuse ESB closes SSH connection and doesn't respond to subsequent connection if features:install fails to find one of the bundles listed.

Fuse ESB 4.3.1-fuse-00-00 goes into bad state if one of the bundles listed in features is not available while doing features:install. It should have shown error message regarding features:install failure however, Fuse ESB goes into really bad state and closes remote SSH connection. Once this happens it rejects all the subsequent SSH connections. It also messes up JMX MBean and if you try to connect JConsole (I connected using pid and not JMX URL) I see servicemix and Karaf MBeans missing. Only activemq and aries.blueprint MBeans are visible.

It even failed to stop Fuse ESB using bin/stop command.

To Reproduce the issue:

1. Modify system/org/apache/servicemix/apache-servicemix/4.3.1-fuse-00-00/apache-servicemix-4.3.1-fuse-00-00-features.xml file in Fuse ESB installation.

2. Add following line to examples-cxf-camel-nmr feature:

<bundle>mvn:org.apache.servicemix.examples/nonExistent-bundle/4.3.1-fuse-00-00</bundle>

3. Start Fuse ESB using bin/start command.

4. When Fuse ESB is completely up connect to this instance using ssh. (ssh -p 8101 -l smx localhost)

5. do features:install examples-cxf-camel-nmr. This will cause SSH connection to close and any subsequent attempts will fail.

NOTE: I have already applied fix fo ESB-1391 so JAXB API mismatch issue is not playing it's role here.
