I solvedthe problem by recreating my local source repo (and added the instructions for doing this as comments in update.sh). Since then I have not had any errors where I couldn't update because of local changes.

Thanks for the build, it is saving me a great amount of time.
I just stumbled upon a compiler exception, and do not know where it should be reported.
I know that bugs against official releases should be reported to
	http://java.sun.com/webapps/bugreport
but what about bugs against mlvm ?

Just for the record, here is the program raising the compiler exception:
	public class C {
		public Object test(java.dyn.MethodHandle mh) throws Throwable {
			return mh.<Object, Object>invokeExact(null);
		}
	}


Thanks in advance for any insight,
