Proof step 6 from proof isarray-okarray-01 (previous step)

st[r -- _type] .type = mkarraytype(ty0), ty0 ≤ ty, r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st) ⊦ okarray(r, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 5:
st[r -- _type] .type = mkarraytype(ty0), is_typevalue(st[r -- _type]), r -- _type ∈ st, ty0 ≤ ty, r ∈ st, okarray(r, ty0, st) ⊦ r = jvmref, okarray(r, ty, st)
