Proof step 3 from proof validref-array (previous step)

¬ is_integervalue(st[r -- _length]), validref(str, r, mkarraytype(ty), st) ⊦ r = jvmref, val2int(st[r -- _length]) = st[r -- _length] .intval

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ validref(str, r, mkarraytype(ty), st) ∧ r ≠ jvmref → is_integervalue(st[r -- _length])

Rule argument
