Java 7 Update 9 と Java 6 Update 37 リリース

To date all Critical Patch Updates (CPUs) for Java 7 have been odd
numbers (JDK 7 Update 1, i.e. 7u1, 7u3, 7u5, etc.), while limited
update releases have been even numbers (7u2, 7u4, 7u6, etc.). Since the
August 2012 Security Alert release required the use of version numbers
originally planned for a later CPU, Oracle will increment the release
number for all subsequent Java 7 and Java 6 releases by two numbers in
order to continue having CPUs as odd numbers and limited updates as
even numbers.

The next Java CPU release, scheduled for October 16, 2012, will be renamed to Java SE 7u9 and Java SE 6u37.
