*hach .. that's fixed by the most recent change in MultipleSelectionModelBase (wasn't aware you did change sooo much ;)

The boundaries of this fix are getting a bit too blurry (as is the other bug report [JDK-8189228](https://bugs.openjdk.java.net/browse/JDK-8189228) ;) for my taste.  

Options either:

- keep this focused on the IOOB error
- find/open an new issue about the incorrect clearSelection impl in MultipleSelectionModelBase

or:
- explicityl widen the scope of this to include the clearSelection bug

My preference would be the first.
