Rick Hillegas commented on DERBY-1180:
--------------------------------------

Committed 4c at subversion revision 398594. Derbyall ran cleanly with 4a before 
the MessageId migration and I did not rerun it against 4c. I did rerun the 
jdbc4 tests against 4c and they passed.

Unfortunately, this patch introduces another instance of the following build 
warning which has been discussed on derby-dev. I believe that Knut Anders has a 
plan for fixing these:

    [javac] 
/home/rh161140/derby/mainline/trunk/java/client/org/apache/derby/client/am/LogicalConnection40.java:43:
 warn
ing: getTypeMap() in org.apache.derby.client.am.LogicalConnection implements 
getTypeMap() in java.sql.Connection; return
 type requires unchecked conversion
    [javac] found   : java.util.Map
    [javac] required: java.util.Map<java.lang.String,java.lang.Class<?>>
    [javac] public class LogicalConnection40

> Add vacuous implementations of missing JDBC4 methods

> If you run the VerifySignatures test, you will see a lot of JDBC4 methods 
> which don't appear in our implementation yet. We need to add vacuous 
> implementations for these methods which raise 
> SQLFeatureNotSupportedExceptions. Most of these methods won't need any more 
> attention because they refer to features (like xml and national strings) 
> which we don't support. We will open additional JIRAs for the methods which 
> need non-vacuous implementations.
