查了点资料，问题的原因我基本是弄清楚了。但要从根本上解决的话，插件的整个实现思路估计要大手术，甚至有可能根本无法做到。我得仔细想想……
一个临时方案是给启动参数加上 -Djdk.reflect.useDirectMethodHandle=false，你可以先试一试救急。但未来 Java 版本中这个参数会被移除。
如题，启动时报错，Openjdk 18 以下为报错抛出的异常 21:24:14 [警告] Exception encountered when loading plugin: HAProxyDetector java.lang.InternalError: java.lang.IllegalAccessException: static final field has no write access: net.md_5.bungee.netty.PipelineUtils.SERVER_CHILD/io.netty.channel.ChannelInitializer/putStatic, from class java.lang.Object (module java.base) at java.base/jdk.internal.reflect.MethodHandleAccessorFactory.newFieldAccessor(MethodHandleAccessorFactory.java:167) at java.base/jdk.internal.reflect.ReflectionFactory.newFieldAccessor(ReflectionFactory.java:176) at java.base/java.lang.reflect.Field.acquireOverrideFieldAccessor(Field.java:1184) at java.base/java.lang.reflect.Field.getOverrideFieldAccessor(Field.java:1153) at java.base/java.lang.reflect.Field.get(Field.java:428) at net.andylizi.haproxydetector.bungee.BungeeMain.onEnable(BungeeMain.java:102) at net.md_5.bungee.api.plugin.PluginManager.enablePlugins(PluginManager.java:265) at net.md_5.bungee.BungeeCord.start(BungeeCord.java:285) at net.md_5.bungee.BungeeCordLauncher.main(BungeeCordLauncher.java:67) at net.md_5.bungee.Bootstrap.main(Bootstrap.java:15) Caused by: java.lang.IllegalAccessException: static final field has no write access: net.md_5.bungee.netty.PipelineUtils.SERVER_CHILD/io.netty.channel.ChannelInitializer/putStatic, from class java.lang.Object (module java.base) at java.base/java.lang.invoke.MemberName.makeAccessException(MemberName.java:955) at java.base/java.lang.invoke.MethodHandles$Lookup.unreflectField(MethodHandles.java:3494) at java.base/java.lang.invoke.MethodHandles$Lookup.unreflectSetter(MethodHandles.java:3485) at java.base/java.lang.invoke.MethodHandleImpl$1.unreflectField(MethodHandleImpl.java:1637) at java.base/jdk.internal.reflect.MethodHandleAccessorFactory.newFieldAccessor(MethodHandleAccessorFactory.java:145) ... 9 more
