Can anyone ID this wild legume?

This plant came up in a pot, and I can't figure out what it is. It has pea flowers, so definitely a legume, but I have yet to see one open, although it's already set one seed pod, so they have to open sometime. The leaves are not sensitive to touch. I thought it was a pigeon pea, but the seeds are wrong. The seed pod is a long, thin, sword-like pod that sticks straight up (you can see one to the right if you look hard). It's not a sicklepod, because they're cassias, and the leaves are much different.

I've searched and searched, but can't find anything online to identify it.
