Proof step 9 from proof junkref-addobj (previous step)

newref(r0, st), junkrefs(str, r ' + refs0, (addobj(r0, class, fis, st)[r -- _type]) .type, addobj(r0, class, fis, st)) ⊦ r0 = jvmref, junkrefs(str, r ' + refs0, st[r -- _type] .type, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ¬ junkrefs(str, refs, ty, st) ∧ newref(r0, st) → ¬ junkrefs(str, refs, ty, addobj(r0, class, fis, st))
Proof step 8:
¬ (¬ junkrefs(str, r ' + refs0, (addobj(r0, class, fis, st)[r -- _type]) .type, st) ∧ newref(r0, st)), newref(r0, st), junkrefs(str, r ' + refs0, (addobj(r0, class, fis, st)[r -- _type]) .type, addobj(r0, class, fis, st)) ⊦ r0 = jvmref, junkrefs(str, r ' + refs0, st[r -- _type] .type, st)
