Hi Jason, yeah this one is really awkward and I can confirm I've seen this one just recently. With the same setup. But didn't really bother to get down further now cause the objects where actually persisted. To my knowledge the transaction manager should be provided by aries therefore a specialized transaction tooling shouldn't be required but I might be wrong. As soon as I find some time I'll try to dig into this :)
