And obtained the following new goals

Proof step 18:
⊦ r -- sk ∈ st → r ∈ st
Proof step 19:
((jvmref -- mkfs(class, void_type, `initstate' .field) ' = rk ⊃ shortval(sho); st[jvmref -- mkfs(class, void_type, `initstate' .field) '])) = initval(undone), jvmref -- mkfs(class, void_type, `initstate' .field) ' ∈ st, rk ∈ st, is_shortvalue(st[rk]), jvmref ∈ st ⊦ st[jvmref -- mkfs(class, void_type, `initstate' .field) '] = initval(undone), st[jvmref -- mkfs(class, void_type, `initstate' .field) '] = initval(error)
