Kathey Marsden updated DERBY-285:
---------------------------------
Attachment: derby285.diff
Fix for DERBY-285 Network Client should not print non-ascii token separators in
message when it cannot connect to the server to retrieve the error message
This patch changes network server to send the complete message in its own
locale instead of just the message arguments and delimiters if the exception is
severe enough to terminate the connection. This will eliminate the special
characters and provide a more readable message.
I also cleaned up the code a bit in this area. I removed the extra logging for
the severe exceptions as these will already be logged as part of the normal
Derby error logging.

> If Network Client cannot connect to the database to retrieve an error
> message, it will print only the message tokens, the non-ascii token
> separators, and derby log location. It would be good if at least the message
> could be formatted to present a better message to the user without the
> non-ascii characters.
> To reproduce try a database shutdown. Because the database is shutdown, the
> client cannot retrieve the actual message from the server. It therefore just
> prints the tokens.
> Start network server
> java org.apache.derby.drda.NetworkServerControl start
> $ java org.apache.derby.tools.ij
> ij version 10.1
> ij> connect 'jdbc:derby://localhost:1527/wombat;create=true';
> ij> connect 'jdbc:derby://localhost:1527/wombat;shutdown=true';
> ERROR 08006: DERBY SQL error: SQLCODE: -1, SQLSTATE: 08006, SQLERRMC:
> wombat[]08006.D[]Database 'wombat' shutdown.[](server log:derby.log)
> ij>
> Note: The actual offending characters have been replaced in the output in
> this bug by []. This is because they break Jira XML retrieval!
