I am facing the same issue. A sample application to replicate this issue can be found: https://github.com/linkedin/datahub Of course, it is a big project so it would take some effort to understand it. But if we just use one of its module: https://github.com/linkedin/datahub/tree/master/metadata-jobs/mce-consumer-job and run this module's jar file. I am seeing the same error reported. environment: jdk 1.8.0 skywalking version: 8.1.0 ``` o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalConfigurationAnnotationProcessor': Instantiation of bean failed; nested exception is java.lang.ClassFormatError: Duplicate interface name "org/apache/skywalking/apm/agent/core/plugin/interceptor/enhance/EnhancedInstance" in class file org/springframework/beans/BeanWrapperImpl 11:01:55.512 [main] ERROR o.s.boot.SpringApplication - Application run failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalConfigurationAnnotationProcessor': Instantiation of bean failed; nested exception is java.lang.ClassFormatError: Duplicate interface name "org/apache/skywalking/apm/agent/core/plugin/interceptor/enhance/EnhancedInstance" in class file org/springframework/beans/BeanWrapperImpl at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean(AbstractAutowireCapableBeanFactory.java:1318) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBeanInstance(AbstractAutowireCapableBeanFactory.java:1213) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:556) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:516) at org.springframework.beans.factory.support.AbstractBeanFactory.lambda$doGetBean$0(AbstractBeanFactory.java:324) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:226) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:322) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:207) at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:90) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:707) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:533) at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:143) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:758) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:750) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:397) at org.springframework.boot.SpringApplication.run(SpringApplication.java:315) at com.linkedin.metadata.kafka.MceConsumerApplication.main(MceConsumerApplication.java:23) Caused by: java.lang.ClassFormatError: Duplicate interface name "org/apache/skywalking/apm/agent/core/plugin/interceptor/enhance/EnhancedInstance" in class file org/springframework/beans/BeanWrapperImpl at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:757) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:468) Caused by: java.lang.ClassFormatError: Duplicate interface name "org/apache/skywalking/apm/agent/core/plugin/interceptor/enhance/EnhancedInstance" in class file org/springframework/beans/BeanWrapperImpl ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
