And obtained the following new goals

Proof step 96:
fis .keys = instfields(class), validFields(r, fis, addobj(r, class, fis, st)), newref(r, st), class+∃(str, class), validref(str, r, mkclasstype(class), addobj(r, class, fis, st)), fs ' × refval(refs .first) ∈ fis, fs ' ∈ instfields(class), validrefs(str, refs, ty, st) ⊦ refs = [], r = jvmref, is_abstract(class), validrefs(str, r ' + refs, mkclasstype(class), addobj(r, class, fis, st))
