That code was not added, it was excluded from executing on macOS. And as the reason for that excluded code the [JDK-7184956](https://bugs.openjdk.org/browse/JDK-7184956) was referenced. But current failure is different. On my system it fails due to wrong "frame" location, it jumps from the "expected" location. In Swing that expected location is calculated by the JPopupMenu.adjustPopupLocationToFitScreen so we can mimic that logic in the test. Or we can test the large menu to check that the popup overlaps the dock.
