    jboss-cli-client.jar cli.disconnect() hangs when called from groovy script

      I am trying to follow the instructions from:

       

      https://community.jboss.org/wiki/AdvancedCLIScriptingWithGroovyRhinoJythonEtc

       

      I have copied the groovy script and things seem to work as expected, but the script hangs on the disconnect. I have simplified the script to:

       

      import org.jboss.as.cli.scriptsupport.*

       

      cli = CLI.newInstance()

      cli.connect()

      cli.disconnect()

       

      and still the script hangs.

       

      I am connecting to a JBoss EAP 6.1.0 instance running on my Linux localhost. I have tried with 32-bit and 64-bit 1.6.0 and 1.7.0 JDK's with the same result.

       

      When I do a kill -3 on the script, I get some things that seem to point to xnio:

      The script functions correctly in that I am able to retreive the start time and compute the uptime, but the script doesn't seem to properly disconnect from the server.

       

      Does anyone have any pointers? Thanks,
