Given the following Xtend code:
class XtendClass {
	
	@Test
	def void testMethod() {
		println(newArrayList('foo','bar','baz').toUpperCase)
	}
	
	def toUpperCase(Collection<String> allStrings) {
		allStrings.forEach[toUpperCase]
	}
}

the compiler generates :

  @Test
  public void testMethod() {
    ArrayList<String> _newArrayList = CollectionLiterals.<String>newArrayList("foo", "bar", "baz");
    this.toUpperCase(_newArrayList);
    InputOutput.<void>println(null);
  }

note 'void' is used as type parameter.
