/**
* CGLIB Dynamic Proxy Weaving mode Weaving implemention is dynamic proxy Every
* target service object has its DynamicProxyWeaving object
*
* problem:
*
* memory leak is more entwined in cglib. The leak can be removed by having
* cglib loaded by a different classloader than the one for the web app. The
* solution is to move the cglib jar and the asm jar to the shared lib directory
* of Tomcat. http://users.cis.fiu.edu/~downeyt/webdev/memory_leaks.shtml
