FULL PRODUCT VERSION :


ADDITIONAL OS VERSION INFORMATION :
Windows 7 64bit Professional

A DESCRIPTION OF THE PROBLEM :
Calling Node.snapshot() anywhere in the SceneGraph causes an unrelated SwingNode to resize to its preferredSize. The SwingNode in question is in a StackPane which normally stretches it to fit.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the example below and press "Snapshot" button


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Layout should not change, SwingNode should be stretched to fit in StackPane
ACTUAL -
SwingNode resized to preferred size.
If the window is then manually resized it goes back to filling the window.

REPRODUCIBILITY :
This bug can be reproduced always.
