Deepa Remesh commented on DERBY-1130:
-------------------------------------

I was going to post a release note about the existing application impact. But 
based on what Dan just said, this change in the method does not look correct 
and maybe we need to revert it. Any thoughts on this? Other options I can think 
of are:

1) Move the check of connectionAttributes into getConnection method. This way 
we throw the exception(that we cannot set databaseName attribute on a data 
source) when getConnection is called. 

2)  Go back to the first solution (derby-1130-v1.diff) which just ensures that 
database name set using setConnectionAttributes does not get used by client 
driver. This is more like what is being done in embedded driver , i.e, we just 
ignore the databaseName attribute. Also, modify the error message to explicitly 
indicate "Derby datasource property" and thus differentiate it from 
databaseName "attribute".

3) other options ?

Please provide feedback about how to proceed on this issue. Thanks.
