You used to be able to, around Java 5 release, but not anymore.  They 
recognized that it was wrong and retracted it.  They used to claim that 
you didn't need to worry about it until the EDT was started, but field 
reports showed their assumptions where wrong.

The main problem with this was action listeners and other call backs 
that would fire while the Swing classes were being constructed. 
However, from the perspective of the Java memory model, there's no safe 
publication either unless you add some.  It's all EDT now, even during 
class construction.
