      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_172-ea"
      Java(TM) SE Runtime Environment (build 1.8.0_172-ea-b03)
      Java HotSpot(TM) 64-Bit Server VM (build 25.172-b03, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Windows 7 and 10

      A DESCRIPTION OF THE PROBLEM :
      I have reported the bug JDK-8194265. So you provide the the early build 172, i test it. And I am really disappointed. Yes, the crash is fixed, but we don't see the file content.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      See also html5rocks/tutorials/file/dndfiles
      See Example: Slicing a file.

      or

      http://papaparse.com/demo

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The callback reader.result should return the file result in callbackhandler reader.onload.
      ACTUAL -
      Error. I don't see any alert message in one of the callback handlers.
      Currently we don't see the result of reading the file.

      REPRODUCIBILITY :
      This bug can be reproduced always.
