But from the bug it follows that SUN result depends on long-to-int
convertion.
So you never know if result if positive (OK) or negative (Exception).
I vote just to do it right and to ignore buggy RI behaviour in this case.

The reason I have started to do this is that the following stress

There's a heck of a lot wrong with intern().

other points I've made about permature optimisation)

you just do a pointer compare) is, in most cases,
