Sunitha Kambhampati commented on DERBY-1130:
--------------------------------------------

Thats makes sense. Thanks Deepa for the explanation.  
The patch (d1130-client-v1.patch) looks good to me.  My +1 for commit.

> Currently this is allowed for client but should be disabled.  I think it is OK to change
because we have documented that client will be changed to match embedded for implementation
defined behaviour.   Hopefully its use is rare as most folks would use the standard setDatabaseName.
 Still there should be a release not when the change is made and it would be better to change
it sooner than later:
> Below is the repro.

> D>java DatabaseNameWithSetConnAttr
> ds.setConnectionAttributes(databaseName=wombat;create=true)
> ds.getDatabaseName() = null (should be null)
> FAIL: Should not have been able to set databaseName with connection attributes
> Also look for tests  disabled with this bug number in the test checkDataSource30.java
