目前，我正在运行redis6与acl和mtls与c#客户端刚刚好。我正在尝试更新我们的java端，以便也使用acl和mtls，但是遇到了一些问题。我目前主要专注于MTL，还没有取得任何进展。这可能是用户的错误，在尝试使用java之前，我已经有5-6年没有使用java了，所以请给出建议。不知道什么或如何真正从这个错误的进展，我做了谷歌搜索并不成功真的。非常感谢您的帮助，我已经很久没有使用java了，所以很可能是问题所在。

版本：
莴苣版本：6.0.0.m1（在本地windows上运行）
redis版本：6.0.5（本地运行linux虚拟机）
笔记：
c#客户端工作正常，所以怀疑这是redis服务器的问题。
redis uri（在设置前以我的真实代码打印）：rediss://localhost:6379
