Hi All!
I got stuck with async feature - user manual does not get any example and I all my tries to continue processing in another thread was failed. This process always is processed in main thread :

 <start-state name="start">
 <transition name="default" to="first" />
 </start-state>
 <state name="first" async="true">
 <event type="node-enter">
 <script name="first-node-enter-script">
 <expression>
 java.lang.System.out.println("IN THE FIRST STATE");
 java.lang.System.out.println(java.lang.Thread.currentThread().name);
 </expression>
 </script>
 </event>
 <transition name="default" to="end" />
 </state>
 <end-state name="end">
 </end-state>
