      A DESCRIPTION OF THE PROBLEM :
      Double.parseDouble(null) throws NullPointerException instead of NumberFormatException.

      This is inconsistent with the Javadoc and the behavior of Long.parseLong().

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Call Double.parseDouble() with null param.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      throws NumberFormatException
      ACTUAL -
      throw NullPointerException

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      public static void main(String[] args) {

      System.out.println(System.getProperties().toString());

      System.out.println("Running Long.parseLong(null)");

      try {
      Long.parseLong(null);
      } catch (NumberFormatException nfe){
      System.out.println("Caught NumberFormatException");
      } catch (NullPointerException npe){
      System.out.println("Caught NullPointerException");
      }

      System.out.println("Running Double.parseDouble(null)");

      try {
      Double.parseDouble(null);
      } catch (NumberFormatException nfe){
      System.out.println("Caught NumberFormatException");
      } catch (NullPointerException npe){
      System.out.println("Caught NullPointerException");
      }
      }
