> I accidentally stumbled into a rather awkward bit of error handling.
> On an IJ session running client/server, I tried:
> ij> connect 'jdbc:derby://localhost:1527/brydb';
> ij> prepare seeMenu as '';
> ERROR 08006: A network protocol error was encountered and the connection has been terminated:
A PROTOCOL Data Stream Syntax Error was detected.  Reason: 0x9,236. Plaintext connection attempt
to an SSL enabled server?
> On the Network Server side, I see:
> Sat Jun 09 09:28:51 PDT 2012 : Execution failed because of a Distributed Protocol Error:
 DRDA_Proto_SYNTAXRM; CODPNT arg  = 2414; Error Code Value = e. Plaintext connection attempt
from an SSL enabled client?
> org.apache.derby.impl.drda.DRDAProtocolException: Execution failed because of a Distributed
Protocol Error:  DRDA_Proto_SYNTAXRM; CODPNT arg  = 2414; Error Code Value = e. Plaintext
connection attempt from an SSL enabled client?

> It seems like the error handling could be improved here, for what is essentially a syntax
error on my part.
