Not excluding volatile also break covariant implementations: | public class BeanInfoDoubleCovariantImpl extends BeanInfoNumberCovariantImpl | { | public Double getProperty() | { | return null; | } | | public void setProperty(Double value) | { | } | } | | public class BeanInfoNumberCovariantImpl | { | public Number getProperty() | { | return null; | } | | public void setProperty(Number value) | { | } | } | Excluding volatile takes care of them too. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099930#...
