[External] : How build an abstract method?

[Mark Roberts]

That’s what I’m doing.  My problem must be I’m using the wrong thing for
the MethodBuilder handler argument.  What do you suggest?

An abstract method does not have code. You shouldn't be calling withCode,
which always generates a Code attribute, which is exactly what you don't
want. If you are calling from ClassBuilder, call withMethod instead of
withMethodBody.

MethodBuilder.withCode won’t allow 0 length body.  Don’t see how to create
an abstract method and define its parameters.



Thank you,
