Bad version number in .class file

当你修改了项目的jdk,然后报错如下:


03:55:40,664 WARN  [ClassLoaderManager] Unexpected error during load of:org.jboss.resource.metadata.mcf.ManagedConnectionFactoryDeploymentGroup

java.lang.UnsupportedClassVersionError: Bad version number in .class file


这样需要修改一下jboss或者tomcat 的jdk
