FULL PRODUCT VERSION :
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Fedora Linux 4.4.5-300.fc23.x86_64 GNU/Linux

EXTRA RELEVANT SYSTEM CONFIGURATION :
The same issue when booting with kernel-4.2.3-300.fc23.x86_64.

A DESCRIPTION OF THE PROBLEM :
Java process starts using more and more memory when setting ProgressBar progress to -1 until it fills both ram and swap.

I'm getting the same memory leak with jdk 1.8.0_74, 1.8.0_73 and 1.8.0_45.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Make a simple JavaFX application with ProgressBar.
Set ProgressBar progress value to -1 somewhere in the code.
Start the application.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Simple JavaFX application with moving progress bar.
ACTUAL -
Java process gradually uses more and more memory until both raw and swap are full in just a few minutes.

REPRODUCIBILITY :
This bug can be reproduced always.
