ArrayIndexOutOfBoundsException for method call with too few type arguments

[eric-milles]

Consider the following:

void test(Type[] array) {
  array.sort(true, Comparator.<Type>comparing({ it.foo }).reversed())
}

Type inferencing and syntax highlighting break down at "comparing" due to supplying one type argument for a method that expects two.
