Proof step 2 from proof init-error (conclusion)

⊦ initerror(class, st[jvmref -- mkfs(class, void_type, `initstate' .field) ', initval(error)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

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

Rule argument
