There is 22% regression in NodeMemory.ChoiceBox occurred in build 8.0-controls-scrum-h186.
Here are the results:
 h185: 501
 h186: 391 objects, -22% (-110 objects)

The values mean that now we able to create 391 ChoiceBox objects (instead of 501) till we reach memory limit.

Steps to reproduce:
> cd JFX_WS/tests/performance/NodeMemory
> ant
> java -client -Xms64m -Xmx64m -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/NodeMemory.jar"
  nodememory.ChoiceBoxTest -render true -allocCnt 10

build 8.0-controls-scrum-h186 contains changes javafx-ui-controls/src/javafx/scene/control/PopupControl.java
done as part of fix for "RT-27077: Regression: HelloTooltip tooltip is shown in plain text".


I have created heap dump files for 100 ChoiceBox objects (run the above test with "-render true -allocCnt 10 -maxAlloc 100 -sleep true")
for builds 185 and 186. Here is the list of additional objects which are created in case build 186 is used:
