Add a tool to generate the class filtering configuration of an application
To simplify the creation of the classloader-filtering.xml file, a tool can be created to analyze the application and generate the filtering configuration (like the Weblogic Classloader Analysis Tool: http://download.oracle.com/docs/cd/E17904_01/web.1111/e13706/classloading.htm#BABHJGJJ ).
In the context of PaaS, the automatic generation of the classloader-filtering.xml file could be done during deployment (and enabled/disabled by a configuration parameter in the application descriptor).
