<Swing Dev> Native look and feel on linux [2]

[Yan]

High!

I've conducted talks with Ubuntu devs:
https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1581835

Altogether: This behavior exists in latest openjdk. There are two ways
to set LAF:
1) hardcoding using method
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()). In
gnome DE this call makes LAF==GTK. In other DE==Metal (LAF depends on
openjdk, not distro).
2) Do not set any LAF in program, use System default settings (config
file swing.properties). Due to some bugs, in Ubuntu default is Metal,
previously was GTK.

The request is to make hardcoded default LAF==GTK for all Linux
distributions, or at least for KDE, Xfce, MATE and Cinnamon. There are a
lot of Java apps (both closed-source and open-source) which hardcode
system LAF. And they look ugly on linux, the workaround is to use
_JAVA_OPTIONS=-Dswing..., but every time I run any java app I see
annoying "Picked up _java_options ..."

What I see now is: when I do not hardcode LAF in my java app it looks
Metal on Windows and GTK on Linux. When I hardcode I see Native LAF on
Windows and Metal on Linux ¯\_(ツ)_/¯
