<Swing Dev> Swing dev>[10] Review request for JDK-8189253: [macos] JPopupMenu is inadvertently shown when using setComponentPopupMenu

[Manajit Halder]

Hi Semyon,

Regression is cause by JDK-8080729 <https://bugs.openjdk.java.net/browse/JDK-8080729>. The fix can’t be reversed since it is the choice between addChildWindow or orderWindow. Went through code flow related to the issue but didn’t find any other better place in code to handle this issue. The best way to fix the issue would be to avoid retargeting of events (MOUSE_ENTER and MOUSE_EXIT) between MOUSE_PRESS and MOUSE_RELEASE on the parent window (when the mouse is actually on the child window). Therefore request you to review the webrev.00.

Regards,
Manajit
