Jason van Zyl closed MNG-5042.
------------------------------
Resolution: Fixed
> Regression: CloningClassLoader causes StackOverflowError in groovy
> ------------------------------------------------------------------
>
> Key: MNG-5042
> URL: https://jira.codehaus.org/browse/MNG-5042
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Class Loading
> Affects Versions: 3.0, 3.0.1, 3.0.2, 3.0.3
> Reporter: Patrick Staton
> Attachments: test-plug.zip
>
>
> 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".
