As Sridhar suggested, you will find this discussed by searching the forums.

The technical specification is under JLS - 5.1.7 Boxing Conversion...

If the value p being boxed is true, false, a byte, a char in the range \u0000 to \u007f, or an int or short number between -128 and 127, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2.
