Description Mikhail Kondratyev 2006-09-18 12:36:49 UTC 
Steps to reproduce:
 - create a new TRS sample
 - Deploy the project and associated J2EE application
 - set breakpoint at ReserveAirline activity
 - set breakpoints also at ReserveVehicle, ReserveHotel activities (this is also
suggested in the tutorial)
 - start debugging by running HasNoReservations test
 - debugger will stop at first breakpoint
 - switch to sources, make sure the BPEL variables window is opened
 - select this window, make it active
 - start pressing F7
Press F7 about ten times - the NPE will be thrown:
