FULL PRODUCT VERSION :
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows 10 (64 bit)

EXTRA RELEVANT SYSTEM CONFIGURATION :
Running at 200% DPI scaling (192 DPI).

A DESCRIPTION OF THE PROBLEM :
On Windows, the minimum & maximum size properties of the Stage class don't scale to the current DPI settings, unlike all other drawing coordinates. The explicit size properties (setWidth/setHeight) do scale but setMinWidth, setMaxWidth, setMinHeight & setMaxHeight do not. Any values passed to them are interpreted as unscaled pixels. This causes a mismatch with all other drawing coordinates at DPI settings greater than 125% when the new DPI scaling mechanism of Java SE 8u60 is active.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the program under "Source Code". It draws a single window containing a black rectangle surrounded by white margins, and then sets minimum and maximum stage sizes based on the rectangle size. Try resizing the window between minimum and maximum sizes and see what happens.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
At any DPI setting, minimum window size should show the entire black rectangle with thin white margins on all four sides. Maximum window size should then add a lot of white space to the margins.
ACTUAL -
At 192 DPI (= 200% of standard), minimum window size shows only a fraction of the black rectangle. Maximum window size shows entire rectangle with thin white margins, i.e. what *should* appear at minimum window size.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
None, as JavaFX currently does not provide any official way to obtain current DPI scaling.
