I tried to let windows7 built-in firewall  pass my java.exe, No any effect.
I must close the firewall, as Alan said, then all OK.

For the firewall I do a probe, not few applications cannot success to
pass as well, even mmplayer from ms self.
Anyway, The issue not a core or focus, through may be a good help that
doc the case.

BTW, Alan, what about the exception translate class?
