Mike Matrigali commented on DERBY-6785:
---------------------------------------
could you try the following. Create a new 10.10 database on the 10.10 target
machine and see if you can cause the same problems trying to access it from
your 10.11 client. Trying to understand if the problem is the software in
general or maybe with just with the demo database provided with 10.10.
Do you get same errors in your test environment from 10.11 to older releases
than 10.10 also?

> Key: DERBY-6785
> URL: https://issues.apache.org/jira/browse/DERBY-6785
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.10.2.0
> Environment: Win 7, Win 8, Mac OSX and Ubuntu 14.04
> Reporter: tariq rahiman
> Fix For: 10.11.1.3

> Attachments: derby.log, log.zip

> 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 ?
