当我试图启动tomcat时，在部署axis2模块时，我得到类强制转换异常．
我已经启用了EnableChildfirstClassLoading财产。当我检查类加载(使用-verbose)时，有些类被加载了两次。[Loaded org.apache.axis2.engine.MessageReceiver from file:/irv_test/cipsm/SecureLinkTestingNEW/SLInstaller1/app4.0/tomcat/webapps/axis2/WEB-INF/lib/axis2-kernel-1.6.2.jar]
这个类从同一个jar位置加载两次。
Axis Version: 1.6.2
Tomcat: 8
OS: Redhat Linux
下面是跟踪:

EnableChildFirstClassLoading在Axis2 1.6.2和1.6.3中被破坏。看到axis2 - 5720。
