Chris, thanks for your comments. I'm kind of thinking the same - I actually also don't really like my result of merging the strings of code so much.
I'll go on and prepare a smaller change set only addressing the real bugs. I also agree to switching the Linux implementation to getifaddrs at the time the Java 10 branch opens to gain experience with that without shipment pressure. Stay tuned :) Christoph > -----Original Message----- > From: Chris Hegarty [mailto:chris.hega...@oracle.com] > Sent: Dienstag, 12.
