Proof step 3 from proof unchNorec-field (previous step)

st[r -- _type] .type = mkclasstype(class), r = jvmref ∨ r ≠ jvmref ∧ st[r -- _type] = st0[r -- _type] ∧ (is_classtype(st[r -- _type] .type) → (∀ fs. fs ' ∈ instfields(st[r -- _type] .type .class) → st[r -- fs '] = st0[r -- fs '])) ∧ ( is_arraytype(st[r -- _type] .type) → st[r -- _length] = st0[r -- _length] ∧ (∀ i. 0 ≤ i ∧ i < st[r -- _length] .intval → st[r -- i '] = st0[r -- i '])), fs ' ∈ instfields(class) ⊦ st[r -- fs '] = st0[r -- fs '], r = jvmref

And obtained the following new goals

Proof step 2:
st[r -- _type] = st0[r -- _type], st0[r -- _type] .type = mkclasstype(class), fs ' ∈ instfields(class), ∀ fs0. fs0 ' ∈ instfields(class) → st[r -- fs0 '] = st0[r -- fs0 '] ⊦ r = jvmref, st[r -- fs '] = st0[r -- fs ']
