Proof step 18:
fis .keys = statfields(class0), validref(str, fis[mkfs(class0, ty, fieldvar) '] .refval, ty, st), is_referencevalue(fis[mkfs(class0, ty, fieldvar) ']), type∃(str, ty), initdone(class0, addclass(class0, fis, st)), mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), tdname∃(str, class0), mkfs(class0, ty, fieldvar) ' ∈ fis, is_reftype(ty) ⊦ ty = void_type, class0 = `java.lang.Object' .class, validrefval(str, fis[mkfs(class0, ty, fieldvar) '], ty, addclass(class0, fis, st))
