Hi Looks like a transaction is executed accross N threads and therefore fails. Is it the case?

I use remote statefull session bean to implement large files transfers between application tires. My statefull bean uses BEAN transaction management. When I issue UserTransaction::commit() an IllegalMonitorStateException is thrown. If I invoke SFSB locally it works, but remote calls throw that Exception. I've prepared a sample to illustrate that problem: https://github.com/ksmigrod/remotestatefull Unfortunately it is a monstrosity using Arquillian and two TomEE 7.0.4 containers. Passing local test is method localUpload of me.noip.ksmigrod.experiments.remotestatefull.CheckTest class. Failing remote test is method uploadViaRest of the same class. Is it a misconfiguraton on my part, a flawed flow control or a bug in TomEE?
