Proof step 24 from proof validstatfield-put-array-norefval (previous step)

okval(val, st[r1 -- _type] .type .type), validstatfield(str, sk, st) ⊦ is_referencevalue(val), is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st[r1 -- i ', val]) → validfield(str, jvmref, sk, st[r1 -- i ', val]))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ is_indexkey(sk) → ¬ validstatfield(str, sk, st)
Proof step 23:
okval(val, st[r1 -- _type] .type .type), validstatfield(str, sk, st), is_fskey(sk) ⊦ is_referencevalue(val), (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st[r1 -- i ', val])) ∧ tdname∃(str, sk .fs .class) ∧ sk ∈ statfields(sk .fs .class)
