I worked around the problems with managedTransaction.global by commenting out the policySet ps2 in the definitions.xml file in payment-java-contribution. (This was commented out previously, but was changed to uncommented in revision r776633.)
With this change, I can start the FullApp, but I get a problem when I open a browser window for http://localhost:8080/scatours. The application page displays, along with a pop-up dialog saying "TypeError: scaToursCart is undefined". If I close this dialog, the travel application seems completely broken, with none of the controls doing anything. Is anyone else seeing this problem? Any ideas as to what is causing it? Simon
