// Lifecycle notes: objects are owned where they will be called; in other words
// FooObservers are owned by C++-land, and user-callable objects (e.g.
// PeerConnection and VideoTrack) are owned by Java-land.
// When this file (or other files in this directory) allocates C++
// RefCountInterfaces it AddRef()s an artificial ref simulating the jlong held
// in Java-land, and then Release()s the ref in the respective free call.
// Sometimes this AddRef is implicit in the construction of a scoped_refptr<>
// which is then .release()d. Any persistent (non-local) references from C++ to
// Java must be global or weak (in which case they must be checked before use)!
//
// Exception notes: pretty much all JNI calls can throw Java exceptions, so each
// call through a JNIEnv* pointer needs to be followed by an ExceptionCheck()
// call. In this file this is done in CHECK_EXCEPTION, making for much easier
// debugging in case of failure (the alternative is to wait for control to
// return to the Java frame that called code in this file, at which point it's
// impossible to tell which JNI call broke).
