      Hello,

      When I click kill thread button on /monitoring page, I got following error:

      Caught unhandled exception with ID 53bf818a-5713-408c-aebe-0578be8d7232
java.lang.UnsupportedOperationException
	at java.base/java.lang.Thread.stop(Unknown Source)
	at PluginClassLoader for monitoring//net.bull.javamelody.internal.model.Action.stopThread(Action.java:554)
	at PluginClassLoader for monitoring//net.bull.javamelody.internal.model.Action.killThread(Action.java:540)
	at PluginClassLoader for monitoring//net.bull.javamelody.internal.model.Action.execute(Action.java:292)

      Issue does not occur when I click same button on Jenkins instance based on Java 17

      Looks like Thread.stop method was removed from Java 21
