Proof step 3 from proof validref-no-len (conclusion)

⊦ ¬ r -- _length ∈ st → (validref(str, r, mkarraytype(ty), st) ↔ r = jvmref)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ validref(str, jvmref, ty, st)
Proof step 2:
⊦ validref(str, r, mkarraytype(ty), st) ∧ r ≠ jvmref → r -- _length ∈ st

Rule argument
