Subject [jira] Commented: (DERBY-4799) IllegalArgumentException when generating error message on server
Date Tue, 14 Sep 2010 08:21:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12909144#action_12909144
] 

Tiago R. Espinha commented on DERBY-4799:
-----------------------------------------

I'm confused now. By looking at your patch, I see that you use "server.DEFAULT_ENCODING" to
obtain the bytes, which is in fact UTF8.

Shouldn't all the DRDA commands and arguments until now be using EBCDIC?

My changes do go into this method and rather than using a .length() call, I use the CCSID
manager (whichever it is currently) to obtain the length in bytes.

> 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: 0x12. Plaintext connection attempt
to an SSL enabled server?
> Printed to the console by the server:
