NoSuchMethod Error AgentBuilder - Can't Start Web Application

[echua]

Spring MVC
SpringBoot 2.1.2

Trying to use the PetClinic example but still cannot get this work. I get errors. Also, for the application, I am using the SpringBootServletInitializer rather than the ServletContextInitializer like in the PetClinic example.

@SpringBootApplication
@EnableScheduling
public class Application extends SpringBootServletInitializer {

public static void main(String[] args) {
	// Stagemonitor.init();  ****
	SpringApplication.run(Application.class, args);
}

public Application() {
	super();
	setRegisterErrorPageFilter(false);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
	return application.sources(Application.class);
}

@Override
public void onStartup(ServletContext servletContext) throws ServletException {
	super.onStartup(servletContext);
	......
}

[m java.lang.NoSuchMethodError: net.bytebuddy.agent.builder.AgentBuilder$Identified$Extendable.asDecorator()Lnet/bytebuddy/agent/builder/AgentBuilder;

Can you confirm the version of ByteBuddy? That method was removed in later versions.

[echua]

Checking the lib directory.

byte-buddy-1.9.7.jar
byte-buddy-agent-1.9.7.jar

[jpfourny]

That explains it. Stagemonitor will not work with anything above 1.8.11, in my experience. 1.9.x contains binary incompatible changes and 1.8.12+ seems to cause test failures and JVM crashes (at least with IBM OpenJ9).

[echua]

What do you suggest to fix this?

[jpfourny]

Down-grade ByteBuddy to 1.8.11.
