Proof step 10 from proof validstatfield-subset (previous step)

sk .fs = mkfs(class, ty, fieldvar), initdone(class, st), initdone(class, st0), st ⊆ st0, validstatfield(str, sk, st) ⊦ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st0) → validfield(str, jvmref, sk, st0))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ is_indexkey(sk) → ¬ validstatfield(str, sk, st)
Proof step 9:
sk .fs = mkfs(class, ty, fieldvar), is_fskey(sk), validstatfield(str, sk, st), st ⊆ st0, initdone(class, st0), initdone(class, st) ⊦ validfield(str, jvmref, sk, st0) ∧ tdname∃(str, class) ∧ sk ∈ statfields(class)
