         * To support statically linked native method implementation we create
         * weak stub functions with the same names as the expected JNI functions
         * (long and short names). These will be discarded by the linker if
         * proper functions are available at link time.
         * 
         * The weak stub with the short JNI name just calls the weak stub with
         * the long name.
         * 
         * The weak stub with the long name calls _bcResolveNative() which will
         * try to resolve the native method against dynamically loaded JNI libs.
         * If _bcResolveNative() finds a matching symbol in a dynamic lib or an
         * implementation has previously been registered using JNI
         * RegisterNatives() that will be stored in the native method pointer
         * passed to it and returned. The stub will call the implementation
         * returned by _bcResolveNative(). If no implementation can be found
         * _bcResolveNative() throws an UnsatisfiedLinkError and doesn't return
         * to the stub.
         * 
         * The limitation of this approach is that RegisterNatives() only works
         * for dynamically linked native methods and can only be used prior to
         * the first call of such a method. Native methods can never be rewired
         * or unregistered.
