Ant and firewall problem [message #299732]

Hi,

I have problems when running Ant scripts in separate VMs (no problem
when running in the same VM). If I disable my Firewall no problem at all.

If the firewall is enabled, there is no real error but no output in the
console and sometimes the tasks does not seem to be started.

The java executable is trusted and excluded from any firewall rule and
there is no entry about any blocked port in the firewall log ;-(

Could anyone explain that phenomenon? How exactly does the Ant run in
the external VM communicate with eclipse - via sockets?

The firewall is Agnitum Outpost Firewall Pro. Anyone with the same
problems out there?

Thanks in advance,
Jan

The console output from the separate VM Ant run is communicated back to
Eclipse via a socket.
The port is determined at launch time using the first free port on localhost
using org.eclipse.jdt.launching.SocketUtil.findFreePort() which just uses
the new ServerSocket(0) support.
