J2cache手动清除缓存时间超长

Question

在手动调用cacheChannel.clear(region)疑陷入死循环，跟踪代码发现RedisGenericCache类里面的keys()方法在符合条件时无法跳出循环具体方法为：

private Collection<String> keys(BinaryJedisCommands cmd) {
   Collection<String> keys = new ArrayList<>();
   String cursor = "0";
   ScanParams params = new ScanParams();
   params.match(this.region + ":*").count(scanCount);
   Collection<String> partKeys = null;
   do {
      ScanResult<String> scanResult = ((MultiKeyCommands) cmd).scan(cursor, params);
      partKeys = scanResult.getResult();
      if(partKeys != null ) {
         keys.addAll(partKeys);
         cursor = scanResult.getStringCursor();
      }
   }while(partKeys != null && partKeys.size() != 0);
   return keys;
}

我跟踪时partKeys.size=6  环境springboot1
