Fun with Melding Java and Python
summary
pgrmi (Python Java Remote Method Invocation) lets Python create shim objects for live Java objects and call methods both ways, using pgrmi (Python Java Remote Method Invocation) to instantiate Java classes, boxing/unboxing primitives, and mapping exceptions to Python. Demos use numpy-based type hints to resolve overloaded constructors, show an eight-level computeIfAbsent callback chain crossing Java↔Python threads, successful proxying of a proxy Runnable into Java thread, arraylist mixing types, pickle-based copy-by-value, and live-attach debugging; open source release is planned.
