5.1.7: JLS does not mention caching of autoboxed longs

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
http://docs.oracle.com/javase/specs/jls/se7/html/jls-5.html#jls-5.1.7

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

But long is cached the same as int and short, but this is not mentioned. Is it an oversight or is it deliberately unspecified.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should state that long is cached or state that long may or may not be cache.
ACTUAL -
long, float and double are not specified.

long is cached, float and double are not, so you cannot assume anything from their absence.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Read the code for OpenJDK instead of the JLS. :(

SUPPORT :
YES
