 Review comment:
   @anuengineer  thanks for review. I remember that discussion, i think reason 
was too many type castings involved in in streams. I dont see any consistent 
approach to tackle it. (We are using streams all over the place) Updated other 
stream usage to foreach loop. In this particular case  foreach doesn't support 
Bitset so left it as it is. Hopefully performance of streams and parallel 
streams will improve in java.
