I have the exact same problem as this person. I'm running the jbpm suite 3.2.3 out of the box. On the websale app. Same error. Just prior to the 1st fork. Get that version error in 2 cases. (1) when the websale app Exits the "Evaluate Web Order" Task just prior to a fork. Get that error on webpage (2) Also when the reminder timer kicks off, get same message but in the console log. I'm running j2se 1.5.0_16. I didnt compile anything, running default suite server and default websale app. Help!
