When passing a refnum across the language barrier there is a small window where a proxy object itself can be garbage collected, its reference count go to 0 and the object be gone when the refnum is dereferenced on the other side. In Go the proxy object is pinned with runtime.KeepAlive. This CL implements the same mechanism in Java by passing the proxy object to native code, ensuring the Java GC can't reclaim it during the call.
