    Description

      I met one issue which will never update znode value successfully when integer overflow (-2147483648) of znode data version using curator to invoke SharedCount#trySetCount(VersionedValue<Integer>, int).
      After dig the limitation logic and found that here could be the root cause.
      https://github.com/apache/curator/blob/master/curator-recipes/src/main/java/org/apache/curator/framework/recipes/shared/SharedValue.java#L196C7-L196C7
      My environment is, curator version: curator-2.10.0, zookeeper version: 3.4.6
