Description

we upgraded to 3.0.4 and now are ant tasks (for product installation) hang.
here is the macro we are using in ant:
<presetdef name="ngsexec">
<sshexec host="localhost"
port="$

{ngs.port.ssh}

"
username="karaf"
password="xxxxxx"
trust="true"
timeout="60000" />
</presetdef>
<ngsexec command="list" />
Basically, Karaf never returns and the ant task times out....
when I set it to verbose, here is the output from a command 'list':
