Javadoc for java.lang.Character still refers to Unicode 4 instead of 5

The javadoc for the java.lang.Character class in JDK7-b66 still refers to old Unicode version:
  "Character information is based on the Unicode Standard, version 4.0."
though Unicode 5.1 change has been integrated into JDK7-b55.

This must be fixed because the Java Language Specification Third Edition [1] states
as follows:
  "The Java platform tracks the Unicode specification as it evolves. The precise
  version of Unicode used by a given release is specified in the documentation of
  the class Character."
