Knut Anders Hatlen commented on DERBY-2017:
-------------------------------------------
The subclasses of EXTDTAReaderInputStream implement both read() and
read(byte[],int,int). Those methods have become rather complex now, since they
handle both switching of buffers and the new status byte. To reduce the
complexity of these classes, do you think it would make sense to define read()
in terms of read(byte[],int,int) so that buffer switching and reading the
status byte only need to be implemented once per class?

> When a LOB stream throws an exception or does not match the specified length,
> the client driver does not raise an exception until it has finished executing
> the statement. Therefore, the statement will be executed (and possibly
> committed) on the server even though the client reports that the statement
> failed.
