Rearranged to better list the several ways:

1. With two Iterators:

   
       
           
               Common value detected : []
               
    setOne position : [] 
               
    setTwo position : []
               
   
           
       
   
   

2. With a single Iterator and Set.contains(Object):

   
       
           Common value detected : [] 
   
       
   
   

3. With a single Iterator and pure OGNL:

   
       
           Common value detected : [] 
   
       
   
   

4. Without Iterators, using OGNL List Selection only (thanks to @AleksandrM for the code):
