I don't have any clues about why your attempt to print the whole
class prints nothing at all.  But I have appended a debugging
routine that does successfully print individual Bodies for me.
I call it out of Transform.apply(Body), to dump the internal
representation as selected phases run (the "alreadyDumping" flag
avoids a Heisenberg effect when I also dump CFGs as they are
built).  You could use similar code to print the bodies of
selected methods from a class.

    // soot.Printer itself needs to create a BriefUnitGraph in order
    // to format the text for a method's instructions, so this flag is
    // a hack to avoid dumping graphs that we create in the course of
    // dumping bodies or other graphs.
    private boolean alreadyDumping = false;

    private void dumpBody(Body b, String baseName) {
	alreadyDumping = true;
	try {
	    java.io.PrintWriter out = openBodyFile(b, baseName);
	    soot.Printer.v().setOption(Printer.USE_ABBREVIATIONS);
	    soot.Printer.v().printTo(b, out);
	    out.close();
	} catch (java.io.IOException e) {
	    // Don't abort execution because of an I/O error, but let
	    // the user know.
	    G.v().out.println("PhaseDumper.dumpBody() caught: " + e.toString());
	    e.printStackTrace(G.v().out);
	}
	alreadyDumping = false;
    }
