下面的是测试代码：userDetails是一个自定义类型UserDetails的实例，调用其他接口（这些接口仅有UserDetails参数）能正常返回结果，一加入其他参数：Calendar、枚举就出上面的异常，请各位大侠给点意见！
ModuleAvailabilityParameters eModuleAvailabilityParameters = new ModuleAvailabilityParameters();
        eModuleAvailabilityParameters.setUserDetails(userDetails);
        eModuleAvailabilityParameters.setStartDate(Calendar.getInstance());
        eModuleAvailabilityParameters.setCityCode(new CityCode("PER"));
        eModuleAvailabilityParameters
                .setAvailabilityStatus(AvailabilityStatus.value2);
        eModuleAvailabilityParameters.setSessionID("777");
        PassengerMix[] passengerConfiguration=new PassengerMix[1];
        passengerConfiguration[0]=new PassengerMix("2A1C-10");
        eModuleAvailabilityParameters.setPassengerConfiguration(passengerConfiguration);
        client.getModuleAvailability(eModuleAvailabilityParameters);
