  31 // the conversions in TernaryNode are not necessary, but they should not cause problems. They did
  32 // this was because the result of Global.allocate(Object[])Object which returns a NativeObject.
  33 // was tracked as an object type on our stack. The type system did not recognize this as an array.
  34 // Then the explicit conversions became "convert NativeArray->Object[]" which is a checkccast Object[]
  35 // which naturally failed.
  36 
  37 // I pushed the appropriate arraytype on the stack for Global.allocate.
  38 
  39 // I also removed the conversions in CodeGen, all conversions should be done in Lower, as
  40 // NASHORN-706 states.

  46 // and primitives. Widest(Object[], int) gave us Object[] which makes no sense. This is used
