Proof step 5 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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ unchangedNorec(r, st, st0) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) ∧ is_classtype(st[r -- _type] .type) ∧ r ≠ jvmref → st[r -- fs '] = st0[r -- fs ']
Proof step 4:
¬ (unchangedNorec(r, st, st0) ∧ fs ' ∈ instfields(st[r -- _type] .type .class) ∧ is_classtype(st[r -- _type] .type) ∧ r ≠ jvmref), st0[r -- _type] .type = mkclasstype(class), unchangedNorec(r, st, st0), fs ' ∈ instfields(class) ⊦ st0[r -- fs '] = st[r -- fs '], r = jvmref
