Hi Yan,
If your application sets LaF explicitly in the code, you cannot override
it with swing.properties.
The Look-and-Feel set using swing.properties file or
-Dswing.systemlaf=<LaF-class> will change the default LaF used by Swing
apps. For example, Swing uses Metal Look-and-Feel by default on Linux
platform: If the application does not explicitly set its LaF, the app
will be displayed in Metal LaF. If you change 'swing.systemlaf' property
to GTK, the application will use GTK LaF.
If the application explicitly sets its Look-and-Feel at runtime, then
that application will be run using the LaF it set. You cannot change it.
Regards,
Alexey

You can put swing.properties file to <JRE>/lib directory as described

The contents of the file would be:
swing.systemlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel
This property file will set GTK LaF for all applications that use this
JRE to run.
High! I've did what you've said, placed file with this line in
/usr/lib/jvm/java-7-openjdk-amd64/lib/ , but nothing have changed. Maybe
I do wrong something?
Once again, I have simple java app, which sets LAF using this:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
and I have no env variables like _JAVA_OPTIONS
