oops. Why did they not document the list of warnings you can suppress?
Apparently you can't just leave the list blank.

Here is my current understanding, quoted from
http://mindprod.com/annotations.html#SUPPRESSWARNINGS

In JDK 1.5 an annotation was introduced called SuppressWarnings.
Unfortunately, it will be ignored until JDK 1.6. You just insert the
annotation prior to a class or method telling which sort of warning
you want suppressed. e.g.

// Turn off warnings about failing to use generics for the whole class
@SuppressWarnings( "unchecked" ) public class MyClass
  {

  // Suppress warnings about missing serialVersionUID
     @SuppressWarnings( "serial" ) public void MyMethod1()
     { /* ... */ }

  // Suppress warnings about unused variables
  @SuppressWarnings( "unused" ) public void MyMethod2()
     { /* ... */ }

  // Suppress warnings about both missing serialVersionUID and unused
variables
  @SuppressWarnings( "serial", "unused" ) public void MyMethod3()
     { /* ... */ }
}

Here are the sorts of warning you can suppress
