Comments
7-na should not be on this issue, the reason is that it affected 7 too. Consequentially I have removed the label.

Added 7-na as it was already backported to JDK 7.

EVALUATION This CR does not need a backport to 6, since the original fix that introduces this problem (4640544) was not backported to 6.

EVALUATION This seems to be a behavior change in Windows 8 but it does highlight that we assume that getsockname will return the local address even for the case that the connection is not yet established.
