ADDITIONAL SYSTEM INFORMATION :
Windows 10 Pro, V1803
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
A DESCRIPTION OF THE PROBLEM :
The undesired additional line breaks occur only when the screen scaling of Windows-10 differs from 100 %.
REGRESSION : Last worked in version 8u161
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the code below with a screen scaling of 125 %.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Same output as when OS screen scaling is set to 100 %, i.e. top and middle button have the same text and bottom button has two lines only.
ACTUAL -
Non programmed line breaks occur on middle and bottom button.
