Issue in color setting

[Michael Strauß]

You're setting a new value in the change listener of the iconColor
property, which then fires off another change notification, and so on.
I guess that you're not getting a new object if you use one of the
predefined constants like "red", which breaks the cycle (as there's no
change notification when the object is the same).
So regardless of whether this worked in JFX22, your code seems wrong.
