Description

If a class is marked with one of the annotations:

• groovy.transform.Immutable  (already supported)
• groovy.transform.KnownImmutable  (already supported)
• net.jcip.annotations.Immutable (supported by Findbugs and IntelliJ IDEA{{)}}
• javax.annotation.concurrent.Immutable (its RetentionPolicy is CLASS, can not be got via reflection)

we will believe their promise and treat them as immutable class.
