FontSize selection exception in RichText demo #24

[lyrachord]

Hi Mikula,
I tried the RichText demo.

Just type lines of text, then select all, so the FontSize selection is clear,
then an exception will throw from JavaFX internel selection model.

Any idea?
Thanks

because the selection cleard, so selected index is -1,
exception as follows

Thanks for reporting. This was a behavior bug in RichTextFX. However, the exception comes from a bug in ComboBox that I reported: JDK-8133228.

Thanks.
Yes, you're right.
Great work!
