> I am unable to use a groovy class as a plexus component in maven 3 because groovy's metaclass mechanism calls Introspector.getBeanInfo() in constructors which in turn calls classloader.loadClass(beanClass.getName() + BEANINFO_SUFFIX) (the class name is "FooBar$__plexus2") which in turn causes CloningClassLoader to create a new clone of the class named "FooBar$__plexus2BeanInfo". When "FooBar$__plexusBeanInfo" is instantiated groovy's the meta class mechanism again calls
> Introspector.getBeanInfo() on "FooBar$__plexus2".
