In generic types, annotations are removed and the annotated type parameter becomes fully qualified, when moving the annotated type to another package

[pewe2024]

The following bug exists in Eclipse IDE 2024-12 (as well as in older versions of the Eclipse IDE):

If you have the Java class

public class Test
{
    public List<@Annotation MovedType> list;
}

and you move the type MovedType to another package, the @Annotation is removed and the type parameter MovedType becomes fully qualified.

The class will look like that, afterwards:

public class Test
{
    public List<destinationpackage.MovedType> list;
}

Instead, only the import for MovedType (which is omitted here) should change.

The attached file

TestProject.zip

contains an eclipse project, that can be used to reproduce the error.

If you move the contained file TestProject/src/sourcepackage/MovedType.java by either dragging and dropping it to TestProject/src/destinationpackage or by using Refactor -> Move..., the file TestProject/src/staticpackage/Test.java will show the error.
