Proof step 8 from proof validsubset-addobj-01 (previous step)

fis .keys = instfields(class), newref(r, st), class∃(str, class), validfieldinits(fis, st) ⊦ r = jvmref, valid⊆(str, st, addobj(r, class, fis, st)), is_abstract(class), ∃ r. refval(r) ∈ fis .vals ∧ junkref(str, r, st), class+∃(str, class) ∧ (sk × refval(r0) ∈ fis → ¬ junkref(str, r0, st))

User applied rule exists right

And obtained the following new goals

Proof step 7:
