JDK6 and 7 are updated again. Lots of security fixes and general bug fixes. Java SE 7 Update 3 & Java SE 6 Update 31 Released 14/Feb/2012 It seems that we really should start using Java 7 to compile and test code. The big question is, does your code base compile with Java 7? That might seem like a silly question, but I found lots of code at work that does not compile.
