Proof step 33 from proof validstatfields-addclass (previous step)

fis .keys = statfields(class), validfieldinits(str, fis, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class) ⊦ class = `java.lang.Object' .class, (initdone(class0, addclass(class, fis, st)) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st))) ∧ tdname∃(str, class0) ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(class0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ class ≠ class0 → ¬ mkfs(class0, ty, fieldvar) ' ∈ statfields(class)
Proof step 32:
¬ class ≠ class0, fis .keys = statfields(class), validfieldinits(str, fis, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class) ⊦ class = `java.lang.Object' .class, (initdone(class0, addclass(class, fis, st)) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st))) ∧ tdname∃(str, class0) ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(class0)
