David Van Couvering commented on DERBY-1090:
--------------------------------------------

Hi, Olav.  It's not clear to me what a committer needs to do with this patch.  You have checked
the box saying you intend it for inclusion to the project, but you also say other, alternate
patches are on  the way.  Do you want a committer to commit this, or is it just for review?

> 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
