tariq rahiman commented on DERBY-6785:
--------------------------------------

What you described in your comment is correct

"Client is running latest 10.11 software.
target is running a network server running on 10.10 software against the demo database
provided with the 10.10 software - I assume that database was build with the 10.10 software
but
have not verified. Some set of catalog queries get marshalling errors as provided in JIRA
description, reporter to provide specific query."

> I have downloaded 10.11.1.1 and 10.10.2.0 from Apache Derby download and installed them
in 2 separate machines.
> I have a GUI client that connects to the toursdb database of both versions using a JDBC
connection that makes uses of derby.jar, derbyclient.jar and derbynet.jar
> I use the latest JDBC drivers from 10.11.1.1 to connect to both the database versions.
The drivers I make use of are derby.jar, derbyclient.jar and derbynet.jar
> Connection to 10.10.2.0 is successful, but when I try to Alter/Drop Tables and Views,
Create an Index or try to retrieve column information of tables, i get the below exception:
> The classpath settings for the two environments are identical and If i replace the derby.jar,
derbyclient.jar and derbynet.jar of the latest release with the 10.10.2.0 ones, it works fine
with 10.10.2.0. 
> So my question is backward compatibility of the latest Apache Derby JDBC drivers. Can
I use 10.11.1.1 jars to connect to 10.10.2.0 ?
