[macosx] incompatibility between system and JRE for images in clipboard

    Details

      Description

      FULL PRODUCT VERSION :
      java version " 1.7.0_40-ea "
      Java(TM) SE Runtime Environment (build 1.7.0_40-ea-b28)
      Java HotSpot(TM) 64-Bit Server VM (build 24.0-b47, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Mac OS X 10.7.5

      A DESCRIPTION OF THE PROBLEM :
      Images copied in the clipboard by a system application can't be retrieved in the JRE, and images copied in the clipboard by the JRE can't be pasted in a system application, like Preview.

      REGRESSION. Last worked in version 6u45

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run the test case included in this report.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      When I copy an image in Preview, I expected that the second message dialog box would display " Image available in clipboard " .
      When the 3rd last message dialog box is displayed, I expected I could open in Preview or paste in other application a 100x100 pixels black image.
      ACTUAL -
      The second message dialog box displayed " No image in clipboard " .
      After the 3rd last message dialog box, I couldn't paste an image in an other application.

      REPRODUCIBILITY :
      This bug can be reproduced always.
