Sporadic NoClassDefFound initing a DTO: RestPackage.Literals

This one is coming and going with absolutely no predictability, including coming and going (with a restart) on the same machine.
It occurs in generated DTO code, on a RTC 2.0 RC4 base. All I can think of is some strange OSGi related plug-in dependency loading problem but that's a stretch.
Here's the exception stack. Any insight or experiments to run would be greatly appreciated. Some substitution done in "<>".
