I think so, yes.  Not "instantiated" as others pointed out but 
initialized. But yes, regardless.

I believe you can get around this by making VERSION final.  The compiler 
is allowed (possibly required?) to copy final static values as a kind of 
constant, in order to avoid this kind of unneeded initialization.

class A
{
  static final String VERSION = "1.0b";
}
