> Hello, 
> I am not entirely sure on the technical issues behind this problem, they seem to stem deep into the platform dependent components of the classloader. 
> On windows, when loading a class both from within groovy and from the java side through the GroovyClassLoader, the returned class is the same class, and can be checked with a simple equality check. But when the same code is run on linux, the two classes returned are different classes. Even running an `isAssignableForm` will fail between the two. 
> I have only seen the behavior on classes referenced by annotations so far.
> It is difficult to describe the complex load behavior that replicates the issue, as such I have built a simple example instead. Please see the attached example project. It has prebuilt run configurations for IDEA that utilize WSL for testing the linux side of the issue. 
> This issue is new to groovy 4, and did not exist in groovy 3. I am testing using JDK 17 from adoptium. 
>  
> Please let me know if any other additional information would be useful.
>  
> Thank you,
> Trevor Flynn
