问题
When attempting to run Cruise Control as a service (in this case on Windows 7, 64bit) I receive the error:
com.thoughtworks.xstream.converters.ConversionException: Cannot construct net.sourceforge.cruisecontrol.BuildLoopInformation as it does not have a no-args constructor
The full error message is:

It might be a little difficult to get Java 6 since it is not provided on Java official website.
Instead of installing Java 6, I used the method described in this blog:CruiseControl 2.8.4 and JDK7:
or replace xstream-1.2.2.jar and xpp3_min-1.1.3.4.O.jar files both in lib/ and ebapps/dashboard/WEB-INF/lib/ with xstream-1.4.1.jar and kxml2-2.3.0.jar respectively.
It worked!

Turns out that something in Java 7 doesn't play nice, so just rollback to Java 6.
