java.lang.LinkageError: LinkageError while defining class:org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
我實現的RESTEasy使用WebSphere 6.1和的RESTEasy 2.1.0.GA
細節誤差如下：
`Caused by: java.lang.LinkageError: LinkageError while defining class: org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher Could not be defined due to: (org/jboss/resteasy/plugins/server/servlet/HttpServletDispatcher) bad major version at offset=6 This is often caused by having a class defined at multiple locations within the classloader hierarchy. Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature.
