Proof step 2 from proof initerror-02 (conclusion)

⊦ initerror(class1, st[r -- i ', val]) ↔ initerror(class1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ initerror(class1, st) ↔ ¬ ¬ (jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st ∧ st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(error))

Rule argument
