Hi Sergey,
It seems when SynthPanel.updateStyle is called,
private void updateStyle(JPanel c) {
SynthContext context = getContext(c, ENABLED);
style = SynthLookAndFeel.updateStyle(context, this);
}
it calls getContext() which in turn calls SynthContext.getContext() with
style variable.
private SynthContext getContext(JComponent c, int state) {
return SynthContext.getContext(c, style, state);
}
Now, "style" variable seems to be null at this point in
SYnthPanelUI.java and
it only gets updated after getContext() call when it calls then next
line SynthLookAndFeel.updateStyle(context, this);
I could not remove the html file as I am getting some serialization
issue if I moved from applet to main based so I retained applet based
test, as of now. Also, due to it being applet, I am not sure how to run
them over installed l&f inside the test.
Modified webrev with test issues rectfied

Hi, Prasanta.
I have few small notes.
- Did you check why the null value was passed to this method?
- It seems that the tests are passed by default. It would be good to
run them over the installed l&f. In this case they will fail before
the fix.
- Is it possible to remove the html files from the tests?
- The tests also have some common issues, the Swing components are
accessed on non-edt thread. some unnecessary commented code, etc.

Hi All,
Please review a subitem fix of JDK-7190554
<https://bugs.openjdk.java.net/browse/JDK-7190554> where some closed
regression test is failing with Nimbus L&F.
Issue was we were getting NPE
