Proof step 4 from proof validref-addobj-this (previous step)

fis .keys = instfields(class), class ≤ class0, newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), tdname+∃(str, class0), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, r = jvmref ∨ (addobj(r, class, fis, st)[r -- _type]) .type ≤ mkclasstype(class0) ∧ ¬ junkref(str, r, addobj(r, class, fis, st)), is_abstract(class)

Proof step 3:
fis .keys = instfields(class), class ≤ class0, newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), tdname+∃(str, class0), junkref(str, r, addobj(r, class, fis, st)), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, is_abstract(class)
