Knut Anders Hatlen updated DERBY-4799:
--------------------------------------
Attachment: fix.diff
The problem appears to be that DRDAConnThread.writeRDBNAM() uses the length of
the string in characters when it calls writeScalarPaddedBytes().
writeScalarPaddedBytes() expects the length in bytes, and gets confused when
paddedLength is less than buf.length.
The reason why we need at least 18 characters in the name in order to see the
bug, is that the database name is always padded to at least 18 bytes (DRDA
requirement).
The attached patch (fix.diff) makes writeRDBNAM() use number of bytes instead
of number of characters. I'll see if I can come up with a regression test for
the bug.

> 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:
