>             Project: Derby
>          Issue Type: Bug
>          Components: JDBC
>    Affects Versions: 10.3.0.0

> Clob.setCharacterStream behaves differently depending on whether you use the 
> embedded or the client driver.
> Sample output from the repro:
> (embedded) Initial : 123456789
> (embedded) After   : 12__56789
> (client)   Initial : 123456789
> (client)   After   : 12__
> As can be seen, the client driver truncates the Clob value when it writes to 
> it, whereas the embedded driver does not and instead replaces existing 
> characters with those written to the character stream.
> (BTW: I know the title is not perfectly accurate, but it got so long when 
> explaining that it is when you actually write to the stream returned by 
> Clob.setCharacterStream the result differs.)
