I checked a few of the channel implementations and they throw the expected IAE. It looks like the only ReadableByteChannel that throws ReadOnlyBufferException is the implementation returned by newChannel. So I think the change is okay and not risky. We should try to see if there is any code that is catching ReadOnlyBufferException.
