code: static Object eval(String expression, Options options, Configuration configuration) {
          ELProcessorFactory elpFactory = (ELProcessorFactory) configuration
                  .getPropertyValue(ELProcessorFactory.EL_PROCESSOR_FACTORY_KEY);
          ELProcessor elp = elpFactory.createELProcessor(configuration);
          elp.getELManager().addELResolver(new OptionsELResolver(options));
          return elp.eval(expression);

docs: Note that we have to use a separate {@link ELProcessor} for each evaluation
  as the {@link OptionsELResolver} may not be reused.
