EventQueue.getCurrentEvent() returns incorrect event

    XMLWordPrintable

    Details

    • Subcomponent:
    • CPU:
      generic
    • OS:
      generic

      Description

      Please run the test case provided below
      Note: package name is important to make it work

      Click to the menu and click any MenuItem
      in console you'll see "Modifiers - 0"

      Now make the frame big enough to completely contain popup menu
      (we need to make it lightweight)

      Click to the menu and click any MenuItem
      in console you'll see "Modifiers - 16"

      This is the problem,
      the result has to be the same for both cases

      See evalutaion for more details
