weblogic接收报文解析报文问题？

Question

今天应用在生产环境上接收报文并解析式报了一个错误，然后weblogic控制台就无法登陆了，但是后台应用的服务还在，还可以接收报文。应用在生产环境上运行了几年了都没出现过这样的错误，而且近期也没有修改过应用包括weblogic的任何配置，在接收相同的报文的内容时偶尔会出错，并不是每条报文都会出错。异常信息如下：

org.dom4j.DocumentException: SAX2 driver class weblogic.xml.jaxp.RegistryXMLReader does not implement XMLReader Nested exception: SAX2 driver class weblogic.xml.jaxp.RegistryXMLReader does not implement XMLReader

有的小伙伴可能会指出是jar包冲突的问题，可是这个应用运行了几年了，而且生产环境没变动的情况下应该不是这种问题。weblogic.xml 中参数如下
<prefer-web-inf-classes>true</prefer-web-inf-classes>
求各位大佬给小弟指点。拜谢！
