Crash using sun.misc.Unsafe.static

Hi guys,
the latest jdk6 (jdk6 update 33) fails hard in the compiler if I try to
store the result of unsafe.staticFieldBase() in
a static final field, i.e if it's considered as a constant.
Neither recent jdk7 nor jdk8 crash, only jdk6 (it also failed with
update 21 which is the oldest version I have).
I think it doesn't crash with recent VM because the result of
unsafe.staticFieldBase() is not a real object
with jdk6 but is a real one with jdk7/jdk8 (because of permgen removal)
Is this bug can be fixed or should I just do not do that ?
cheers,
Rémi
