Dag H. Wanvik updated DERBY-4531:
---------------------------------
Issue & fix info: [Repro attached] (was: [Release Note Needed, Repro
attached])
Since this patch removes the regression, I don't believe we require a release
note, so unsetting that flag, and closing.
> Client setCharacterStream closes its Reader argument stream in finalizer

> The javadoc for PreparedStatement.setCharacterStream does not specify that
> the stream passed in will be closed, only that it will read to the number of
> characters specified.
> For the embedded driver, the stream is not closed after execution; the client
> driver, however, will close the stream when the internal stream object
> EncodedInputStream is garbage collected, which can happen any time after the
> statement has been executed.
> I am not sure this a bug vs. the JDBC specification, but it would be nice to
> harmonize client and embedded behavior on this.
