1. 环境信息：

Spring 3.2.10, JDK 1.8, Hibernate 4

2. 运行简单的程序，出现以下错误信息：

3. org.springframework.beans.factory.BeanDefinitionStoreException: Failed to load bean class: com.aio.service.FileListenerRun; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: class path resource [java/lang/Thread$WeakClassKey.class]; nested exception is java.lang.IllegalArgumentException at org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions(ConfigurationClassPostProcessor.java:289) at org.springframework.context.annotation.ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry(ConfigurationClassPostProcessor.java:223) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:630) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:461) at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:389) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:294) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:112) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4853) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5314) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:145) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1408) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1398) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: class path resource [java/lang/Thread$WeakClassKey.class]; nested exception is java.lang.IllegalArgumentException at org.springframework.core.type.classreading.SimpleMetadataReader.<init>(SimpleMetadataReader.java:56) at org.springframework.core.type.classreading.SimpleMetadataReaderFactory.getMetadataReader(SimpleMetadataReaderFactory.java:80) at org.springframework.core.type.classreading.CachingMetadataReaderFactory.getMetadataReader(CachingMetadataReaderFactory.java:102) at org.springframework.core.type.classreading.SimpleMetadataReaderFactory.getMetadataReader(SimpleMetadataReaderFactory.java:76) at org.springframework.context.annotation.ConfigurationClassParser.doProcessConfigurationClass(ConfigurationClassParser.java:175) at org.springframework.context.annotation.ConfigurationClassParser.processConfigurationClass(ConfigurationClassParser.java:154) at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:131) at org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions(ConfigurationClassPostProcessor.java:285) ... 15 more Caused by: java.lang.IllegalArgumentException at org.springframework.asm.ClassReader.<init>(Unknown Source) at org.springframework.asm.ClassReader.<init>(Unknown Source) at org.springframework.asm.ClassReader.<init>(Unknown Source) at org.springframework.core.type.classreading.SimpleMetadataReader.<init>(SimpleMetadataReader.java:53) ... 22 more
   解决方案有两条：
   a. 使用jdk7

   b. 升级spring 4

4. 问题解决

最终选择了jdk7， 然后问题解决。
