RFR (XS): 8006199: [parfait] Possible null pointer dereference at hotspot/src/share/vm/opto/loopopts.cpp

[Vladimir Kozlov]

Albert,

Changes are incorrect. as_Proj() is simple cast so it can't return NULL:

   type##Node *as_##type() const {                            \
     assert(is_##type(), "invalid node class");               \
     return (type##Node*)this;                                \
   }                                                          \
