Java5 introduced covariant return types but we weren't supporting this properly because MethodInfoImpl was taking into account the return type (and declaring class) when doing the equals check. I removed these two checks from the equals. Covariant return types are where you override the method to return a different type. e.g. | public class Something | { | public Object getSomething() {} ; | } | | public class StringSomething | { | // StringSomethings return a String not an Object | @Override | public String getSomething() {} ; | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4012025#...
