Rick Hillegas commented on DERBY-1090:
--------------------------------------

I concur, looks good. JDBC4 tests run cleanly. Derbyall runs cleanly modulo wisconsin noise.
Committed at subversion revision 396028.

> The Javadoc for JDBC4 says this about Connection.isValid:
> boolean isValid(int timeout) throws SQLException
> Returns true if the connection has not been closed and is still valid. The driver shall
submit a query on the connection or use some other mechanism that positively verifies the
connection is still valid when this method is called. 
> The query submitted by the driver to validate the connection shall be executed in the
context of the current transaction. 
> Parameters: timeout - - The time in seconds to wait for the database operation used to
validate the connection to complete. If the timeout period expires before the operation completes,
this method returns false. A value of 0 indicates a timeout is not applied to the database
operation. 
> Returns: true if the connection is valid, false otherwise
