And obtained the following new goals

Proof step 40:
# refs = # sks0, st[r -- mkfs(class0, ty, fieldvar) '] = refval(r0), st[r -- _type] .type = mkclasstype(class), mkfs(class0, ty, fieldvar) ' ∈ instfields(class), validrefs(str, r0 ' + refs, st[r0 -- _type] .type, st), fits(r0, sks0, st), is_obj(str, r, st), ∀ sks1. sks1 ⊑ sks0 ∧ sks1 ≠ [] → st[r0 -- sks1] .refval = (r0 ' + refs)[# sks1] ⊦ r = jvmref, junkref(str, r, st), junkref(str, r0, st), validrefs(str, r0 ' + refs, ty, st), st[r0 -- _type] .type ≤ ty
