[rules-users] Flow Timer causes exception: Caused by: java.util.concurrent.RejectedExecutionException

Hi, I have a flow and a set of rules. In the flow I have a wait state. If the wait state has a timer, when the flow reaches the node it blows up with the following exception ( See Below ), if I remove the timer everything works.
