Leap second + Java + Linux fix (without reboot): /etc/init.d/ntp stop; date; date `date +"%m%d%H%M%C%y.%S"`; date; -- then restart java

Where were you 11 hours ago when we rebooted all of our cassandra and mysql machines? :-)

I didn't really think about it at the time, but right about then (I'm in GMT+10) a Minecraft server (OpenJDK 64-bit, Ubuntu 11.10) I had running got rather upset ...

     2012-07-01 09:59:59 [WARNING] Time ran backwards! Did the system time change?
     2012-07-01 10:01:14 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?

... and stuck on 100% CPU until I noticed it and restarted it this morning. Thankfully no other issues that I've noticed.
