Resolution$NoSuchTypeException

[severous]

    public static void premain(String args, Instrumentation instrumentation) {
        PluginFinder pluginFinder = null;

        try {
            PluginBootstrap pluginBootstrap = new PluginBootstrap();
            pluginFinder = new PluginFinder(pluginBootstrap.loadPlugins());
        } catch (Exception e) {
            return;
        }

        ByteBuddy byteBuddy = new ByteBuddy().with(TypeValidation.of(true));

        AgentBuilder.Default builder = new AgentBuilder.Default(byteBuddy);

        builder.type(pluginFinder.buildMatch())
                .transform(new Transformer(pluginFinder))
                .with(new BytebuddyListener())
                .installOn(instrumentation);


    }
    

public ElementMatcher getMethodsMatcher() {
     
      return ElementMatchers.named("getAlternative")
              .and(ElementMatchers.takesArguments(4))
              .and(ElementMatchers.isStatic());
  }

When I attempted to intercept the first getAlternative method,

[raphw]

Seems like your class loader cannot read class files, or there is an optional type that is missing, so Byte Buddy cannot resolve it.

Either you have to add your own class file resolver, or you have to adjust your instrumentation to not request for that information. Possibly, you can also ignore the error, if it affects an unrelated type instrumentation.

Thank you for your reply. The relevant tutorial suggests modifying it to TypeValidation.of(false). However, I'm unsure if this is safe. In fact, the method bound to the servlet is not the one I intend to intercept.
Additionally, Could you please give me some details about solution
