> Take the following code to copy a sub-stream from a BLOB:
> Blob blob = rs.getBlob(1);
> InputStream stream = blob.getBinaryStream(1000, 2000);
> try {
>   IOUtils.copy(stream, out);
> } finally {
>   stream.close();
> }
> This will loop forever in IOUtils.copy, as the InputStream is returning 0 at end of stream instead of -1.  It probably should return -1 to comply with the Javadoc for InputStream.
> Notes:
> I have not yet checked Blob.getBinaryStream(), or any of the Clob methods, or the client driver.  So some of these may have a similar issue.
