Nacos appears to be incompatible with Java 21.

[narukeu]

Describe the bug
我在 JDK 21 上运行 nacos，发现不能正常运行，查了资料发现这可能是 nacos 对 JDK21 的一个特性不兼容导致的，希望可以解决这个问题。
I ran Nacos on JDK 21 and found that it wasn't working properly. After doing some research, I discovered that this might be due to an incompatibility between Nacos and a feature in JDK 21. I hope this issue can be resolved.

Expected behavior
run nacos without any errors.

Actually behavior
我已经将日志上传到了附件。
I have uploaded the log to the attachment.
error.log

How to Reproduce
run ./startup.sh

Desktop (please complete the following information):

• OS: macOS 14 arm64
• Version nacos-server
• SDK OpenJDK 64-Bit Server VM Temurin-21.0.4+7 (build 21.0.4+7-LTS, mixed mode)

Additional context
Add any other context about the problem here.

Caused by: org.apache.derby.iapi.error.StandardException: A read-only user or a user in a read-only database is not permitted to disable read-only mode on a connection.

No relative nacos' version and jdk version, it just your user has no permission to write dir and file.

那个确实是我的问题，但是现在仍然存在 21 版本不兼容的问题，我重新设置之后，在 Java 21 下运行，报错，然后切换 JAVA_HOME 到 17，发现正常运行。

我看了 nacos 的更新日志说 2.4.2 “解决了 JDK17+” 的启动问题，但是我这里的测试仅仅是 Java 17 启动问题修复了，21 还是不行。

[KomachiSion]

和jdk版本无关，是网络环境问题， 你的环境连接地址服务器失败，超时了

Caused by: java.net.SocketTimeoutException: Read timed out，所以节点无法获取集群节点列表。
