Description

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".

Example stack trace:

If you could attach a test project that recreates the error that would be great (improves the odds of getting this fixed).

Patrick - any chance of getting a test/example project that shows this exception?
