It is possible, but it requires changes on OpenJDK itself. The best
way to resolve this is to discuss the issue directly on the OpenJDK
mailing list. Still, there are a lot of bug reports everywhere when
GTK LAF is used by default due to applications mixing GTK2 and GTK3
calls. I'm not aware if this has been fixed recently or is still an
issue, again it is something to be discussed on the OpenJDK side.

Unless it is clear that GTK is safe to be used and we have good
heuristics in place to know when we must avoid it, we will not enable
GTK by default. There are no bugs tracking this on Ubuntu AFAIK, I
have put this bug back as a confirmed for now and will ask someone to
set its priority to Wishlist. We can track progress that way.

The SilverBlue is called Metal LAF.

This is weird, the systemlaf is set to
com.sun.java.swing.plaf.windows.WindowsLookAndFeel on Windows and
com.apple.laf.AquaLookAndFeel on OSX. Apart from a systemlaf being set
I have no idea why it would be using Metal instead on Windows and OSX.

Again, the best way would be for OpenJDK to allow us to set that on
the swing.properties file. This way users could edit the file to set
what LAF to use when
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName())
gets called.

Title:
  Enable native GTK Look and Feel for non-gnome desktops

Status in openjdk-7 package in Ubuntu:
  Confirmed
Status in openjdk-8 package in Ubuntu:
  Confirmed

Bug description:
  Openjdk-7 and openjdk-8 do not enable native look and feel by default. But they support it. Apps use ugly blue theme, even if the code contains "UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());"
  I've tried Xubuntu 14.04, Ubuntu Mate 16.04 - apps look ugly. (for example logisim)

  To get native LAF you need to use these arguments: _JAVA_OPTIONS 
  -Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel
