Problems while migrating from FEST 1.2 to AssertJ-Swing 3.17

Hello,

there are two problems.

```
JTabbedPaneFixture tabbedPaneFixture = ...;
Component c = tabbedPaneFixture.selectedComponent();
```

The method call selectedComponent() doesn't work because it doesn't exist in the AssertJ-Swing 3.17. How can I solve it ? Or is there any work-around ?

`ComponentFixture cf = ...; `
The class ComponentFixture is in FEST 1.2 but it doesn't exist in AssertJ-Swing 3.17.

Does it work by just replacing the `ComponentFixture` with `AbstractComponentFixture` ?

Thank you in advance.
