[Bug libgcj/18115] New: JNI nio buffer functions only work with byte buffers

["juhal at users dot sourceforge dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The following does not work properly:
Java:
ByteBuffer directByteBuffer = ByteBuffer.allocateDirect(10);
IntBuffer directIntBuffer = directByteBuffer.asIntBuffer();
JNI:
(*env)->GetDirectBufferAddress(env, directIntBuffer);

The reason for the failure is that GetDirectBufferAddress expects that the
buffer is an instance of DirectByteBufferImpl, when in this case it is actually
an instance of IntViewBufferImpl containing directByteBuffer.
