Proof step 6 from proof validstatfields-put-norefval-field (previous step)

ty ≠ void_type, sk ∈ statfields(class0), validstatfields(str, st), okval(val, ty), tdname∃(str, class0), initdone(class0, st) ⊦ mkfs(class, ty, fieldvar) ' = _type, mkfs(class, ty, fieldvar) ' = _length, r = jvmref, is_referencevalue(val), validstatfield(str, sk, st[r -- mkfs(class, ty, fieldvar) ', val]), validstatfield(str, sk, st) ∧ ty ≠ void_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
sk ∈ statfields(class0), validstatfields(str, st), okval(val, ty), tdname∃(str, class0), initdone(class0, st) ⊦ mkfs(class, ty, fieldvar) ' = _length, r = jvmref, ty = void_type, is_referencevalue(val), validstatfield(str, sk, st[r -- mkfs(class, ty, fieldvar) ', val]), validstatfield(str, sk, st)
