FULL PRODUCT VERSION :
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) Client VM (build 25.60-b23, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Windows 7 x64

A DESCRIPTION OF THE PROBLEM :
Cursor on a Node is set manually (e.g. Cursor.HAND on an HBox). The node also has a Tooltip added by Tooltip.install(). The first time the Tooltip appears, it changes the cursor back to default.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- Create a Node with some content (e.g. an HBox with a Label in it)
- Set that node's cursor to something else (e.g. Cursor.HAND)
- Add a tooltip with Tooltip.install(node, tooltip)

When the mouse moves over the node, the cursor changes to the hand (correct).
After short delay, the tooltip appears (also correct) and the cursor changes to default (incorrect)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The cursor should remain as a hand all the time, while the mouse is hovering over the X.
ACTUAL -
The cursor will change to default the first time the tooltip appears.

REPRODUCIBILITY :
This bug can be reproduced always.
