    	Test use org.apache.commons.jelly.core.ModularExceptionBean bean
    	Set an expection and this bean will throw it with  'public void throwIt(String message) throws Throwable;' 
    	
    	Improvements :
    	1. Set a list of expected exceptions as java try catch usual block
    	2. Dissect Exception stack to get the real exception throughout the JellyTagException wrapping with 'cause' var
