      Description

      FULL PRODUCT VERSION :
      openjdk version "1.8.0_91"
      OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3-b14)
      OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Linux 4.6.0-1-amd64 #1 SMP Debian 4.6.2-2 (2016-06-25) x86_64 GNU/Linux

      A DESCRIPTION OF THE PROBLEM :
      When applying an animation with Animation.INDEFINITE as cycle count, the program quickly gobbles up all system memory.

      Tested on label with RotateTransition and TranslateTransition, but may be relevant to other animations or other node/control types.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Create a label.
      2. Create a RotateTransition or TranslateTransition with indefinite cycle count.
      3. Run the animation, and watch memory usage climb.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Memory usage should remain reasonable
      ACTUAL -
      Memory usage quickly climbs up to 4+ GB, and if left alone can turn entire system unresponsive.

      REPRODUCIBILITY :
      This bug can be reproduced always.
