关于cglib的问题，各位老大快来帮忙

纯web项目，项目中用到了cglib中的部分功能，代码如下：
private Object getInstrumentedClass(Class clz)
{
enhancer = new Enhancer();
enhancer.setSuperclass(clz);
enhancer.setCallback(this);
return enhancer.create();
}奇怪的事情出现了，相同的包，当发布到sges-2_1-windows.exe上时，系统运行正常，当发布到sges_ee-2_1-windows.exe上时，程序走到enhancer = new Enhancer();报错，提示信息如下：

原因已经有了，红色部分。
是不是系统中已经有一个老版本的Class，没有相应的Constructor？楼主检查一下看看。
多谢楼上的回复
可我把整个cglib包的源码考到项目中，将对应路径全部修改，仍然是glassfish非企业版没有问题，企业版报错，错误和上面一样。感觉是不是ges企业版和非企业版在部署cglib时有些不同？
上面是我把源代码考到项目里面后运行的结果，大家可以看到路径已经改成com.iss.cglib.proxy.Enhancer 了，cglib的原路径是net.sf.cglib.proxy.Enhancer
