Proof step 30 from proof same-subclasses-01 (previous step)

And obtained the following new goals

Proof step 7:
⊦ same-subclasses-contains(class, str, str0) ↔ same-subclasses(class, str, str0) ∧ (∀ class0. contains(str0, mkclasstype(class), mkclasstype(class0)) → same-subclasses(class0, str, str0))
Proof step 29:
tdname+∃(str0, class0), mkfs(class1, mkclasstype(class3), fieldvar) ' ∈ instfields(class2), class0 ≤ class3, same-subclasses(class, str, str0) ∧ (∀ class0. contains(str0, mkclasstype(class), mkclasstype(class0)) → same-subclasses(class0, str, str0)), tdname+∃(str0, class), class2 ≤ class, tdname+∃(str0, class2), ∀ class0, str0, str, class, tys0. # tys0 < # [] → (same-subclasses-contains(class, str, str0) ∧ contains(str0, mkclasstype(class) ' + tys0 + mkclasstype(class0) ') → tdname+∃(str, class0)) ⊦ class = `java.lang.Object' .class, tdname+∃(str, class0), interface∃(str0, class2)
