FIX: java.text.DateFormat.parse() Throws a NullPointerException

ID: Q177751

The information in this article applies to:

Microsoft SDK for Java, version 2.0x
Microsoft Internet Explorer version 4.0x for Windows NT 4.0
on the following platforms: NT, Win95
Microsoft Win32 Virtual Machine for Java

SYMPTOMS

When the parse() method of the java.text.DateFormat cannot parse a date, the Microsoft virtual machine incorrectly throws a NullPointerException error instead of a ParseException error.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
This bug was corrected in the Microsoft virtual machine contained in the SDK for Java 3.0 and later.

MORE INFORMATION

Steps to Reproduce Behavior

Create a Java project and include the following class:


class Test
{
   public static void main(String[] args)
   {
      try
      {
         java.text.DateFormat Df;
         Df = java.text.DateFormat.getDateInstance();
         Df.parse("Foo");
         System.out.println ("Done.");
      }
      catch(Exception e)
      {
         System.err.println("caught exception");
         e.printStackTrace();
      }
   }
}

java.text.DateFormat is a package that is included with JDK1.1. Build the above code with the JVC that is provided in the SDK2.0x for Java and execute. You will see that the Microsoft virtual machine throws a NullPointerException instead of ParseException as mentioned in the Documentation.
