Proof step 83 from proof validstatfield-putrkvs (previous step)

validstatfield(str, sk, st), validvals(str, rkvs, st) ⊦ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st[rkvs]) → validfield(str, jvmref, sk, st[rkvs]))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ is_indexkey(sk) → ¬ validstatfield(str, sk, st)
Proof step 82:
validstatfield(str, sk, st), validvals(str, rkvs, st), is_fskey(sk) ⊦ (initdone(sk .fs .class, st[rkvs]) → validfield(str, jvmref, sk, st[rkvs])) ∧ tdname∃(str, sk .fs .class) ∧ sk ∈ statfields(sk .fs .class)
