### 2. Environment:
- JDK version: 1.8
- OS: windows10
- TX-LCN version: 5.0.2.RELEASE
- Others: IDEA

还请各位大神帮忙解决

Commencez par RedisStorage.refreshMachines(RedisStorage.java:269), puis suivez l’appel à RedisTemplate.discard et le cycle de vie de la transaction environnante présenté dans la trace de la pile. Reproduisez l’échec avec l’environnement indiqué comprenant JDK 8, Windows 10 et TX-LCN 5.0.2.RELEASE. C’est terminé lorsque l’actualisation des machines ne déclenche plus l’exception de transaction inactive.
