Proof step 43 from proof isarray-update (previous step)

st[r -- _type] = typeval(ty0), ty0 = mkarraytype(ty), r ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st ⊦ r = jvmref, okarray(r, ty, update(r0, fis, st)) ↔ okarray(r, ty, st), r = r0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 42:
st[r -- _type] = typeval(mkarraytype(ty)), r -- _type ∈ st, r ∈ st ⊦ r = r0, okarray(r, ty, update(r0, fis, st)) ↔ okarray(r, ty, st), r = jvmref
