Proof step 5 from proof validrefnotnull-primarray (previous step)

is_primtype(ty) ⊦ r ≠ jvmref ∧ validref(str, r, mkarraytype(ty), st) ↔ okarray(r, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ validref(str, r, mkarraytype(ty), st) ∧ r ≠ jvmref → okarray(r, ty, st)
Proof step 4:
is_primtype(ty), okarray(r, ty, st), r ∈ st ⊦ r = jvmref, validref(str, r, mkarraytype(ty), st)

Rule argument
