(I presume the 'Runable' instead of 'Runnable' was just a typo...) NoClassDefFoundError doesn't mean what you think it means from the name.
It means that an error happened while the class was being loaded. And for reasons that I cannot fathom, when Java added exception chaining, they did not make THIS exception contain the original cause, so the stack traces are ALWAYS mysterious. The best way to debug these is to actually debug them with the debugger. Set exception breakpoints for Exception and Error. You'll probably have to skip a bunch of harmless internal exceptions, but the one before the NoClassDefFoundError is thrown should be the one you want -- hopefully. Often it's because some class that's referenced in the code in question won't load either -- and that's often because a static initializer got an error.
