I don't think this is a threading issue, are you using the @Path annotation anywhere, if so what is the syntax of it? --- On Fri, 4/5/12, Eli Konky <eli...@gm...> wrote: From: Eli Konky <eli...@gm...> Subject: [Simple-support] NullPointerException To: sim...@li... Received: Friday, 4 May, 2012, 1:43 PM Hi all, I'm running on android. I have a multi threaded executor that sometimes crashes with the below error.All my threads share the same strategy and persister: Strategy strategy = new AnnotationStrategy(); Persister persister = new Persister(strategy);When I recreate those two objects on every request the problem goes away, but I thought the persister is thread safe.
