Proof step 6 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; st[jvmref -- mkfs(class1, void_type, `initstate' .field) '])) = initval(error)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
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)
