I've actually set up this property on my eclipse.ini because otherwise I can't download GWT plugin on Eclipse.
I can successfully start Jetty (installed from debian repository) and also other java services so it doesn't seem to be a socket listening issue. Maybe, the issue is do to the way eclipse's jetty is configured... I'll try tonight to figure out where it comes from.
