Proof step 48 from proof junkrefs-put-null-02 (previous step)

∀ st, r, str, ty, i. is_reftype(st[r -- _type] .type .type) ∧ junkrefs(str, acc, ty, st[r -- i ', refval(jvmref)]) → r = jvmref ∨ junkrefs(str, acc, ty, st), is_reftype(st[r -- _type] .type .type), junkrefs(str, r0 + acc, ty, st[r -- i ', refval(jvmref)]) ⊦ r = jvmref, junkrefs(str, r0 + acc, ty, st)
