Proof step 25 from proof pathex-addobj (previous step)

refs = r0 + refs0, fis .keys = instfields(class), validFields(r, fis, addobj(r, class, fis, st)), newref(r, st), validref(str, r, mkclasstype(class), addobj(r, class, fis, st)), fs ' × refval(r0) ∈ fis, fs ' ∈ instfields(class), validrefs(str, refs, mkclasstype(`java.lang.Object' .class), st) ⊦ r = jvmref, refs = [], path∃(str, r, refs .last, addobj(r, class, fis, st))

Proof step 24:
fis .keys = instfields(class), validFields(r, fis, addobj(r, class, fis, st)), newref(r, st), validref(str, r, mkclasstype(class), addobj(r, class, fis, st)), fs ' × refval(r0) ∈ fis, fs ' ∈ instfields(class), validrefs(str, r0 ' + refs0, mkclasstype(`java.lang.Object' .class), st) ⊦ r = jvmref, path∃(str, r, (r0 ' + refs0) .last, addobj(r, class, fis, st))
