MediaPlayer Leaking Native Memory

    Details

    • Subcomponent:
    • CPU:
      generic
    • OS:
      generic

      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_151"
      Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
      Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      When I use the java fx Media Player to play a big mp4 file the native memory explodes to more then 10 gigabytes in a matter of minutes. The heap size however remains the same.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run the following program with a mp4 file with
      Frame width: 1920
      Frame height: 1080
      Data rate: 50008kbps
      Total bite rate: 5144kbp
      Frame rate: 50fps





      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      In a matter of minutes the system will freeze because all RAM is being used.
      ACTUAL -
      Windows freezes and start paging.

      REPRODUCIBILITY :
      This bug can be reproduced always.
