Proof step 19 from proof eq-mod (previous step)

st0[_mode] = throw(r, mkclasstype(class1)), st0 =mode st ⊦ initerror(class0, st), initundone(class0, st), ¬ initerror(class0, st0) ∧ ¬ initundone(class0, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ initerror(class1, st) ↔ (jvmref -- mkfs(class1, void_type, `initstate' .field) ') × initval(error) ∈ st
Proof step 18:
st0[_mode] = throw(r, mkclasstype(class1)), st0 =mode st ⊦ (jvmref -- mkfs(class0, void_type, `initstate' .field) ') × initval(error) ∈ st, initundone(class0, st), ¬ initerror(class0, st0) ∧ ¬ initundone(class0, st0)

Rule argument
