Does this mean you will be wrapping your double pointer interface to
follow the spec?

As an aside, in C++ native methods still take a JNIEnv *, rather than
a JNIEnv as a function argument, and still pass in a double pointer to
JNI calls as argument 0.  I don't understand why everyone keeps
calling the JNIEnv** "this".
