Hello Hans, we sadly have no code for the C++<->Java interaction but a good example is the Python<->Java interaction code in https://github.com/apache/arrow/blob/master/python/pyarrow/jvm.py . This call Java from Python using the jpype1 module and then uses the memory pointers in the Java objects to construct pyarrow objects out of it.
