Verifying this change

Follow this checklist to help us incorporate your contribution quickly and easily:

• Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
• Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• Run mvn -B clean package apache-rat:check findbugs:findbugs -Dmaven.test.skip=true to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.

我自己浏览器和nacos-client测了下，没发现啥问题，内存利用又和1.4.2一样丝滑了。

我印象中这个改动好像是为了解决有slb/nginx之类的负载均衡的时候， 登录失效的问题，改动之后应该对于这个场景又会有问题， 有什么好的版本解决内存问题的时候同时解决这个场景问题吗？

[wyt]

这个我还得试验下，但是应该以优先解决内存问题为主。

先跑下ci， 没问题就合进去，近期发新版本。

帮忙看下2.x是否有相同的问题，提个PR修复一下。

跑失败了嘛，就改了两行代码
