    [ https://issues.apache.org/jira/browse/DERBY-3644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904238#action_12904238

Mamta A. Satoor commented on DERBY-3644:
----------------------------------------

Just commited a change into trunk with revision 990841 which has reverted back the prtocol
level back to 1. I will create another jira for shutdown issue and look into that.

the commit comments were as follows
DERBY-3644 and DERBY-2109

As part of DERBY-2109, shutdown command started accepting optional user name and password.
Bacause of this change in command, the protcol level was bumped up to 2. But this caused all
the network server commands from clients with DERBY-2109 changes to break against a server
without the DERBY-2109 changes. That is because the server checks the protocol level of the
client commands and if they do match with server protocol version, then server will simply
throw an exception about mistmatch of protocol levels and thus causing all the client commands
from post DERBY-2109 clients to break against server with pre-DERBY-2109 changes.

Will create another jira to handle the shutdown command's optional user name and password
parameters.
