[jboss-jira] [JBoss JIRA] Commented: (JBAOP-255) Instanceof expressions and methods overriding with a different return type

[Kabir Khan (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBAOP-255?page=comments#action_12345503 ] 
            
Kabir Khan commented on JBAOP-255:
----------------------------------

class Super
{ 
   Object getFoo(){} 
} 
class POJO extends Super
{ 
   String getFoo(){} 
}

becomes

class Super
{ 
   Object getFoo(){} 
} 
class POJO extends Super
{ 
   String getFoo(){} 
   volatile Object getFoo(){} 
}

The extra volatile method is a "bridge method". (ACC_VOLATILE and ACC_BRIDGE are both 0x00000040).
