Knut Anders Hatlen commented on DERBY-4799:
-------------------------------------------
I think we've been sending the contents of the DRDA commands as UTF-8 all the
time, and only the command headers as EBCDIC. Not sure exactly where the line
was drawn between EBCDIC and UTF-8. I was also a bit surprised that we didn't
use EBCDIC here.
I checked the latest patch on DERBY-4757 and didn't see that it touched this
method. Is this something you've planned to add in the next revision of the
patch? If it already uses UTF-8, I suppose it shouldn't be changed by
DERBY-4757 to use EBCDIC against older clients.

> If you for example try to connect to a non-existing database using the client
> driver, and the name of the database has 18 characters or more, and at least
> one of the characters in the database name is a non-ascii character, the
> server will throw an IllegalArgumentException when trying to send the
> "database not found" message back to the client.
> Example:
> ij> connect 'jdbc:derby://localhost/abcdefghijklmnopqå';
> ERROR 08006: A network protocol error was encountered and the connection has
> been terminated: A PROTOCOL Data Stream Syntax Error was detected. Reason:
