Proof step 7 from proof validref-addarray-same (previous step)

¬ (r ≠ jvmref ∧ ¬ is_valid_ref(str, r, addarray(r, ty, i, st))) ⊦ r = jvmref, junkref(str, r, addarray(r, ty, i, st)), ¬ i < 0 ∧ type∃(str, ty) ∧ ty .jtelemtype ≠ abstract_type ∧ ty .jtelemtype ≠ void_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
is_valid_ref(str, r, addarray(r, ty, i, st)) ⊦ r = jvmref, junkref(str, r, addarray(r, ty, i, st)), ¬ i < 0 ∧ type∃(str, ty) ∧ ty .jtelemtype ≠ abstract_type ∧ ty .jtelemtype ≠ void_type
