And obtained the following new goals

Proof step 15:
⊦ validref(str, r, ty, addclass(class, fis, st)) ↔ validref(str, r, ty, st)
Proof step 17:
type∃(str, ty), jvmref ∈ st, is_reftype(ty), initdone(class2, st), tdname∃(str, class2), mkfs(class0, ty, fieldvar) ' ∈ statfields(class2), tdname∃(str, class0), mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), initdone(class0, st), jvmref -- mkfs(class0, ty, fieldvar) ' ∈ st, is_referencevalue(st[jvmref -- mkfs(class0, ty, fieldvar) ']), validrefval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], ty, st) ⊦ class = `java.lang.Object' .class, class0 = class, ty = void_type, initdone(class, st), mkfs(class, void_type, `initstate' .field) ' ∈ fis, validref(str, st[jvmref -- mkfs(class0, ty, fieldvar) '] .refval, ty, st)
