The "com.apple.macos." prefix for the "useScreenMenuBar" property was deprecated a long time ago, even before the macOS port was integrated to the OpenJDK 7.

Note that if this property is used the next message is printed to the "err":
"com.apple.macos.useScreenMenuBar has been deprecated. Please switch to apple.laf.useScreenMenuBar"

The earliest message about deprecation which I found was in 2006. Its time to delete it.
