Proof step 3 from proof unchNorec-field0 (previous step)

st0[r -- _type] .type = mkclasstype(class), unchangedNorec(r, st, st0), fs ' ∈ instfields(class) ⊦ st0[r -- fs '] = st[r -- fs '], r = jvmref, fs ' ∈ instfields(st[r -- _type] .type .class) ∧ is_classtype(st[r -- _type] .type)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ r ≠ jvmref ∧ st[r -- _type] ≠ st0[r -- _type] → ¬ unchangedNorec(r, st, st0)
