Re: [Jython-dev] Quasi-success with integrating interfaces and new style classes #2

[Leo U. <leo...@ya...>]

Oh yeah, I was able to get the Dynamic proxy method
invocation working, so it is a path that may prove to
work.  Im a little worried about adding another
reflective level of indirection and Im not sure what
impact this would have on object construction time.

The dynamic subclassing appears to be going ok.  I can
generate a subclass and load the bytes but there is
some verification error going on when I try to
reflectively look at the constructor.  It keeps
complaining that Im calling the wrong initialization
method, which is odd since Im invoking the <init> of
the superclass.  There must be a crucial step being
missed in building up the constructor's byte code.
