I am altering the opacity of an Arc from 1.0 to 0.0. The Arc is drawn with a stroke of WHITE color having a width of 3. When I change the opacity, the Arc's stroke remains opaque whereas the fill area is becoming transparent. This is incorrect and not compatible with desktop behavior.

To reproduce the bug, I have attached a sample test. Do the following -
1. Save both the source files in the same directory.
2. Use JavaFX Packager and package the app for mobile platform -

javafxpackager -src . -appClass ArcTest -profile MOBILE -sign

Deploy the App on the emulator as follows -
emulator -Xjam:install=ArcTest.jad

Now press Key 1 few times to choose appropriate fill color that is different from stroke. Press Key 9 a few times. It will alter the opacity. You will see that only filled area is becoming transparent and not the stroke.
