Bryan Pendleton created DERBY-5806:
--------------------------------------
Summary: Trying to prepare statement with no text causes DRDA
protocol exception
Key: DERBY-5806
URL: https://issues.apache.org/jira/browse/DERBY-5806
Project: Derby
Issue Type: Bug
Components: Network Client, Network Server
Affects Versions: 10.10.0.0
Reporter: Bryan Pendleton
Priority: Minor
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.
