Did you try:
List blockList = new Vector();
?
(I don't know if this will work or not - just guessing here...)

I have a java class with a method that takes two arguments. One is a class I
define and the other is a List interface. The call to the method from groovy
works if the List is empty, but fails if the List has elements in it. I get an
error that the second argument is the wrong class and the class type is the
first element of the List. How do I tell it to pass the List to the method?
Vector blockList = new Vector();
blockList.add( salesRollupBlock );
