    Description

      On Windows, a crash can be reproduced in webkit.
      The crash occurs when a number of WebViews with their own WebEngine keep loading pages and is due to an access violation in code that is part of jfxwebkit.dll:

      # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x2c79c043, pid=1076, tid=3680
      #
      # JRE version: Java(TM) SE Runtime Environment (8.0_73-b02) (build 1.8.0_73-b02)
      # Java VM: Java HotSpot(TM) Client VM (25.73-b02 mixed mode windows-x86 )
      # Problematic frame:
      # C [jfxwebkit.dll+0xa9c043]

      We managed to trace this down to code being executed by the js lowlevelInterpreter, which is called in the following way:
