Proof step 18:
fs = mkfs(class, ty1, fieldvar), is_referencevalue(st[r0 -- fs ']), fs ' ∈ instfields(st[r0 -- _type] .type .class), is_obj(str, r0, st), st[r0 -- _type] .type ≤ ty, junkrefs(str, st[r0 -- fs '] .refval ' + refs, ty1, st), ∀ str0, ty0, st0, r1. junkrefs(str0, st[r0 -- fs '] .refval ' + refs, ty0, st0) → junkrefs(str0, st[r0 -- fs '] .refval ' + refs, ty0, st0 -- r1) ⊦ r0 = jvmref, r = r0, junkrefs(str, r0 ' + st[r0 -- fs '] .refval ' + refs, ty, st -- r)
