What's wrong with my brain? :-)
It's a bug in JCC. The code converting lists of objects had a bug with
extension objects, in two places.
With my fix, not yet checked in, your code then fails with a stack overflow
as you didn't actually implement any of the methods in MySearcher that you
declared native in PythonSearcher.
Because there is no local implementation , the code that calls these methods
calls the inherited method instead. That inherited method is the one that
calls the local Python implementation which instead calls the inherited
method and so on ...
Andi..
