Description

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:
