When using the dateTimeEntry ace component in a dataTable fronting a database with a DATE column, a java.sql.Date value will be returned by the ResultSet. When this value is encoded by the dateTimeEntry component, it calls Date.getMinutes(), which has been deprecated since Java 1.1. When getMinutes() is called on the java.sql.Date super class, it throws an IllegalArgumentException as seen below:

We should not use these deprecated methods, and rely on proper Calendar instances instead.
