Now that we support jdk 1.5, use the T.valueOf() factory methods where T

is Boolean, Byte, Short, Character, Integer, Long, Float, or Double.

This has always made sense for Boolean, but with 1.5 they added these
methods everywhere and they are the preferred method for obtaining an
instance of any of those classes unless you absolutely want different
object references.

Since many Integer objects have a low value, the small bit of overhead
incurred for calling these methods should more than make up for itself
in saved memory and garbage collection time.
