Summary

Remove the deprecated macOS-only Swing system Property: com.apple.macos.useScreenMenuBar

Problem

The Swing UI toolkit on macOS supports two implementation System properties, either of which can be used to enable the global menu bar on macOS by setting the value to "true"

• "com.apple.macos.useScreenMenuBar"
• "apple.laf.useScreenMenuBar"

The "com.apple.macos." variant of the "useScreenMenuBar" property was deprecated a long time ago, in Apple JDK 6 and this deprecation was inherited in the initial integration of the macOS port to OpenJDK.

if this property is used the following message is printed to System.err :

"com.apple.macos.useScreenMenuBar has been deprecated. Please switch to apple.laf.useScreenMenuBar"

but it is still currently recognised and honoured.

The earliest message about deprecation which I found was in 2006 and it is long overdue for removal.

Solution

Delete the long-deprecated System property.

Specification

No changes in the specification. This is a JDK implementation property
