org.springframework.expression.spel.SpelParseException
Root exception for Spring EL related exceptions. Rather than holding a hard coded string indicating the problem, it records a message key and the inserts for the message. See {@link SpelMessage} for the list of all possible messagesthat can occur. @author Andy Clement @since 3.0
