Kotlin with AnonymousClassPatchPlugin

[skevy]

Hi there.

Latest JBR 21 build + latest HotSwapAgent build. When changing a class that contains anonymous classes created by the Kotlin compiler, I get an error like:

HOTSWAP AGENT: 23:01:58.968 ERROR (org.hotswap.agent.annotation.handler.PluginClassFileTransformer) - InvocationTargetException in transform method on plugin 'class org.hotswap.agent.plugin.jvm.AnonymousClassPatchPlugin' class 'viaduct/engine/runtime/execution/FieldResolver$fetchObjectSerially$1' of classLoader 'jdk.internal.loader.ClassLoaders$AppClassLoader'

This is a little different from #420 AFAICT.

I'm going to disable the AnonymousClassPatchPlugin in order to workaround this for now, but I wanted to make sure I filed an issue to see if anyone has taken a look at this issue. Note, this is also with the latest version of IntelliJ so it's using a 2.x version of the Kotlin compiler.

One guess I have actually -- I wonder if the plugin doesn't support nested anonymous classes...which seems to be what this is (it's a suspend function).
