On AS7.1.0.CR1b displays following message immediately after deployment and typing localhost:8080/seam-booking to your browser:

The identifier [transient] is not a valid Java identifier as required by section 1.19 of the EL specification (Identifier ::= Java language identifier). This check can be disabled by setting the system property org.apache.el.parser.SKIP_IDENTIFIER_CHECK to true.

When I set that property to false, then the above exception is thrown. This functionality was ok on 7.1.0.Beta1b
