Stefano,
i think i poked through all the jars in JDK 1.4 and did not find
it...hence the question.
Found it!!!
The problem is in the XJavac task that Xerces2 uses to compile stuff 
(probably it's a left-over workaround from an ant bug on the javac task).

Now, not only I can't find the sourcecode of that sucker (I had to 
decompile it with jad (find it attached) but here is the offending part:

 String s = ((String) properties.get( "java.vendor" )).toUpperCase( 
Locale.ENGLISH );
 if(s.indexOf("IBM") >= 0)
 {
              // create an IBM-specific classpath
 }
 else if(s.indexOf("SUN") >= 0 ||
         s.indexOf("BLACKDOWN") >= 0 ||
         s.indexOf("APPLE") >= 0)
 {
          // build the regular classpath
 }

note how the classpath *IS*NOT*BUILT* if neither of the above match!
I would strongly lobby with the xerces people to get rid of that silly task.
