This was fixed by checking the system menu bar every time an item is inserted or removed and removing all menu items that are not owned by JavaFX. This check is done on every insert and remove as JavaFX does not have a clear method inside the MenuBarDelegate class that could be called every time the window gets the focus.

I have now created the new PR: https://github.com/openjdk/jfx/pull/1904

I also have taken into account the very good advice to let the AWT devs take a look at the PR and stated what the fix does , how it works and why we need this fix.
