Fixed in r7045 Actually it's a little more complicated - the abstract class PyTableCode also has to be serializable. But (almost) all code objects that extend PyTableCode are going to be in a separate class loader. (Clamp should enable some change of this. Maybe.) Fortunately, Java provides support for serialization of such classes, through a registration mechanism in subclassed ObjectOutputStream/ObjectInputStream. Take a look at PyJavaType.java for the Java implementation and test_java_integration.py for a Python implementation. Both are based on the blog post in http://weblogs.java.net/blog/emcmanus/archive/2007/04/cloning_java_ob.html
