Hi Claes,
Nice trick. You made MethodType(s) and WeakEntry(s) holding them equal,
respecting the equals()/hashCode() contract. When WeakEntry looses the
referent it is left equal to itself only, which is enough for expunging
it from map.

Hi,
a small improvement can be seen on startup tests that exercise lambdas
and ISC if we change the interning mechanism of MethodTypes slightly
so that lookup can be done without wrapping the lookup key in a
WeakEntry.
