I've reduced the code to this simple sample:
public class NoClassDefFoundSample {
   public void foo() {
     // do nothing
   }

   public static void main(String[] args) {
     NoClassDefFoundSample classDefFoundSample = new 
NoClassDefFoundSample();
     for(int i=0; i < 100000; i++) {
       classDefFoundSample.foo();   // invokedynamic
     }
   }
}

public class NoClassDefFoundBug {
   // bootstrap method
   public static CallSite invokevirtual(Lookup lookup, String name, 
MethodType type) throws Throwable {
     MethodHandle mh = lookup.findVirtual(type.parameterType(0), name,
         type.dropParameterTypes(0, 1));

     CallSite invokerCallSite = new MutableCallSite(mh);

     MethodHandle dynamicInvoker = invokerCallSite.dynamicInvoker();

     CallSite callSite = new MutableCallSite(type);
     callSite.setTarget(dynamicInvoker);

     return callSite;
   }
}

The sample triggers the JIT and the JITed code of the dynamicInvoker() 
throws
the NoClassDefFoundError.
