Thanks for trying the new version and pointing out this. This a bug, we'll fix it and put in a bug fix release 1.2.1 soon. Autostart should be blocked for servlet engine, since tomcat needs to be brought up separately. But this should not prevent you from configuring it.
How do you use our server? in production, development or test? How's your experience with R1.1 on JSP/Serlvet? Any suggestions?
