This just means that getResource gives you a Universal Resource Locator
(URL), whereas IJ.log expects a String. To convert any object to a
String representation, just call its toString() method:

IJ.log(
stack.getClass().getResource("MultiQTVirtualStack.class").toString() );

this is implicit in String concatenations, so the following should also
work:
IJ.log(""+ stack.getClass().getResource("MultiQTVirtualStack.class") );

Otherwise, for you problem at hand, maybe there are several .class files
on your disk/in your jars ?

good luck,
Adrian
