Proof step 11 from proof isarray-put-samefield (previous step)

oktype(val, ty, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_arraytype(st[r -- _type] .type), okarray(r, st[r -- _type] .type .type, st), r ∈ st ⊦ mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, r = jvmref, is_array(r, st[r -- mkfs(class, ty, fieldvar) ', val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
st[r -- _type] .type = mkarraytype(ty0), oktype(val, ty, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_arraytype(st[r -- _type] .type), okarray(r, ty0, st), r ∈ st ⊦ mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, r = jvmref, is_array(r, st[r -- mkfs(class, ty, fieldvar) ', val])
