Robert Burrell Donkin commented on JAMES-1309:
----------------------------------------------
Dunno (I access the Ubuntu box over a network so fiddling with the networking
settings isn't very convenient for me ATM)
IIRC Ubuntu (desktop) ships with default unusual settings which cause issues
for some Java server applications on some JREs. James builds fine on my Gentoo
and Debian boxes. Some similar issues have been reported with HBase on Ubuntu
desktops.
ATM investing the time to prove the cause, coding a fix and then talking
upstream into accept the patch doesn't seem worthwhile to me. I'd be happy to
accept this as a known issue, write it up and forget it. If there's a consensus
for this approach, I'll find some time to give some simple instructions.
