Lanai - Netbeans IDE has BLACK background for the Toolbar and Statusbar

To reproduce this:

1. Download Apache NetBeans 11.2

2. Run it with the latest build of lanai with the metal pipeline enabled:

$ export JAVA_HOME=.../lanai/build/macosx-x64/images/jdk
$ ~/Downloads/netbeans/bin/netbeans -J-Dsun.java2d.metal=true --jdkhome $JAVA_HOME

It can be seen that - the Toolbar at the top and the Statusbar at the bottom are rendered with BLACK background (See attached screenshot)

Note : the background is not BLACK with OpenGL pipeline.
