Merging classes with nested classes fails with "Cannot compute access path" if anonymous package is used

[slarse]

Always, a SpoonException like this is thrown:

spoon.SpoonException: Cannot compute access path to type: Cls$CustomException in context of type: Cls

[slarse]

The above exception seems to always be cast if there is no package statement in the file. For example, this crashes:

class Cls {
    private static class Nested {}

    public static void main(String[] args) {
        Nested nested;
    }
}

But this does not:

package pkg;

class Cls {
    private static class Nested {}

    public static void main(String[] args) {
        Nested nested;
    }
}

As all code in practice is packaged, I will probably not fix this.
