      Description

      From email report on user@:

      It builds something like below (imagine the arrow from A-> B, A-> C,
      B->D, and C->D)
      ---------------------------------------------------------
      Bolt_B
      Spout -> Bolt_A -> Bolt_D
      Bolt_C
      ---------------------------------------------------------

      I get an error below in FLUX.

      Exception in thread "main" java.lang.IllegalArgumentException: Bolt
      has already been declared for id bolt_D
