Just to make things more frustrating; from Jan 14, 2013: http://www.zdnet.com/security-experts-on-java-fixing-zero-day-exploit-could-take-two-years-7000009756/
Then this today: http://www.zdnet.com/java-update-doesnt-prevent-silent-exploits-at-all-7000010422/
Basically Java 7 update 10 created a problem... a BIG problem and it has not been fixed by update 11 and may take a long time to get right.
I guess if you have Java 7 update 9 you are OK.
As for me, I went back to Java 6 update 38
