Kristian Waagan commented on DERBY-4686:
----------------------------------------
Thanks for the patch, Yun :)
The patch looks good. I think we can improve it by verifying that we actually
transfer len bytes, and to avoid infinite loop in the case where there are
fewer than len bytes in the stream.
We can probably reuse error msg SQLState.SET_STREAM_INEXACT_LENGTH_DATA (see
ReaderToUTF8Stream.checkSufficientData).

> It would be better if a transfer buffer was used to facilitate the write.
