The question is: what does a jmethodID map to?  Historically, it maps
to a (_Jv_Method*), and you can't map that to a class.  But perhaps a
jmethodID should be the same as a java::lang::reflect::Method* -
does does have a reference to its declaring class.

Actually, we want to go further: Have Jv_Method be the same
as java::lang::reflect::Method.  That assumes the compiler creates
a compressed data structure, which is lazily unpacked when needed,
as previously discussed.
