  java.util.SimpleTimeZone constructors don't throw NullPointerException when
their 'ID' parameter is null. Time zones with null ID are senseless but can cause
throwing an unexpected NullPointerException when comparing zones, etc.

Here is a test demonstrating the bug.
---------------
import java.util.SimpleTimeZone;

public class NullIDTest {

  public static void main(String args[]) {
    try {
      SimpleTimeZone tz = new SimpleTimeZone(0, null);

      System.out.println("Failed: NullPointerException is not thrown");
    } catch(NullPointerException e) {
      System.out.println("Passed");
    }
  }
}

---------The test output--------
> java NullIDTest
Failed: NullPointerException is not thrown
