variable arguments in java

I have to confess that I totally missed out on Varargs in Java. This is embarrasing. Yesterday I have been searching for a method in Sesame (www.openrdf.org) that takes (among others) 3 Resource instances as parameters. I could not find it although the code compiled and I did call it. Guess why ;-).

I don't think it's a good idea to use that Java 5! language feature. It can lead to poor traceability and to error-prone code. Instead I would always use collections. What do you think?

Here's an example in case someone else missed out on it too:

public class VarargTest {

 public static void func(String p1, String... args) {
  for(String arg : args) System.out.println(arg);
 }
 
 public static void main(String args[]) {
  func("a");  
  func("a","b");  
  func("a","b","c");
 }
}
