Proof step 33 from proof validstatfields-class-01 (previous step)

initdone(class, st), tdname∃(str, class), sk ∈ statfields(class), validstatfield(str, sk, st) ⊦ is_fskey(sk) ∧ jvmref -- sk ∈ st ∧ type∃(str, sk .fs .type) ∧ sk .fs .type ≠ void_type ∧ validval(str, st[jvmref -- sk], sk .fs .type, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
⊦ is_indexkey(sk) → ¬ validstatfield(str, sk, st)
Proof step 32:
initdone(class, st), tdname∃(str, class), sk ∈ statfields(class), validstatfield(str, sk, st), is_fskey(sk) ⊦ validval(str, st[jvmref -- sk], sk .fs .type, st) ∧ sk .fs .type ≠ void_type ∧ type∃(str, sk .fs .type) ∧ jvmref -- sk ∈ st
