And obtained the following new goals

Proof step 7:
⊦ ¬ validstatfield(str, mkfs(class, void_type, fieldvar) ', st)
Proof step 10:
is_fskey(sk), validstatfield(str, sk, st[jvmref -- mkfs(sk .fs .class, void_type, `initstate' .field) ', val]), sk ∈ statfields(class), initdone(class, st) ⊦ mkfs(sk .fs .class, void_type, `initstate' .field) ' = sk, sk .fs .class = class, validstatfield(str, sk, st)
