FULL PRODUCT VERSION :
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)



ADDITIONAL OS VERSION INFORMATION :
Linux Syntax 3.19.0-31-generic #36~14.04.1-Ubuntu SMP Thu Oct 8 10:21:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
On my Kubuntu 14.04 Linux system the ChoiceBox does not properly respond to mouse clicks, or touchpad taps, after a first selection is made. This is true if the first selection comes from a ".getSelectionModel().selectFirst()" call, or from the user.

The problem shows-up with all of the ChoiceBox sample code that I have tested. My mouse and touchpad work fine. I have tried making a jar file of the test, and running that on my Windows system, and that works as expected.


ADDITIONAL REGRESSION INFORMATION:
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Save the test to the file "BadChoiceBox.java".
2. Run: javac -Xlint BadChoiceBox.java
3. Run: java BadChoiceBox
4. In the GUI, in the empty ChoiceBox, select "item2".
5. Then attempt to make a different selection. The ChoiceBox highlights when the mouse moves over it, but it will not click open to allow a different selection to be made.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The ChoiceBox should allow multiple changes of the selected choice item.
ACTUAL -
After the first selection, the ChoiceBox does not allow any subsequent selection.

REPRODUCIBILITY :
This bug can be reproduced always.
