Hi Alpapad ,
there is a problem in the pull request yet in ELResolverPlugin:
- probably "public static void beanELResolverRegisterVariable(CtClass ctClass)" is not called, that is wrong. "public void invalidateClassCache(ClassLoader appClassLoader, CtClass ctClass) is called correctly. It expects that beanELResolverRegisterVariable registers __purge method but it couldn't since it is not called, than it failed in command.
