Hi Ken,
I'm using standalone.
I've observed the problem both in WF 8.2.1.Final and WF 10.0.0.Final. The type of connection, and communication pattern, is the same. This is observable in Windows (I haven't tried any linux flavor) running as Administrator or Windows Service. I've been using JDK 8u20, but it is also observable with the latest JDK release.
I find this connections very intriguing, and I'm hopping to understand what sub-system may be responsible, in order to deal with the problem I described in the forum.
Thanks,
Luís M. Costa
