Description Christopher Sahnwaldt CLA 2007-01-17 09:04:56 EST 
Build ID: M20060921-0945

Steps To Reproduce:
1. In the compiler error preferences, set "Inexact type match for vararg arguments" to "Error".

2. Compile the following class:

public class Foo
{
  public void foo()
  {
    Integer[] array = null;
    varargs(array);
  }

  public void varargs( Number ... o )
  {
  }
}


3. The line "varargs(array);" is marked as an error. The description reads "The argument of type Integer[] should explicitly be cast to Number[] for the invocation of the varargs method varargs(Number ...) from type Foo. It could alternatively be cast to Number for a varargs invocation".
