Proof step 5 from proof initerror-04 (previous step)

st[jvmref -- mkfs(class1, void_type, `initstate' .field) '] = initval(error), jvmref -- mkfs(class1, void_type, `initstate' .field) ' ∈ st, jvmref ∈ st ⊦ (((jvmref = r ∧ mkfs(class1, void_type, `initstate' .field) ' = _type) ⊃ val; initval(error))) = initval(error)

Heuristic if-then-else split applied rule case distinction

And closed the goal!
