How to use

Melon

in

org.jboss.cdi.tck.tests.extensions.configurators.observerMethod

 fruitExtendedList.add(new Melon())

//This would be valid if fruitExtendedList was the list of Fruit but it may 
//not be, as it can also be the list of WaterMelon object. So, we see an invalid 
//condition already.

 melonSuperList.add(new Melon())

//This is valid because melonSuperList can be list of Object, Fruit or Melon and in 
//this entire list we can add Melon type object.
