      Description

      Different behavior between 1.5b51 and 1.4.2_03.

      REPRODUCE;
        
        1) Compile the program

      ::::::::::::::
      test2.java
      ::::::::::::::
      import java.io.*;
      import java.util.*;

      public class test2 {
          public static void main(String[] args) {

              try{
                  String test = "test";
                  String test2 = null;
                  test.equalsIgnoreCase("Apple");
                  test2.equalsIgnoreCase("Apple");
              }catch(Throwable ne) {
                  System.out.println(ne.getMessage());
                  ne.printStackTrace();
              }
          }
      }


        2) Launch "java -showversion test2" in 1.5-beta-b51

      d;\temp>java -showversion test2
      java version "1.5.0-beta2"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
      Java HotSpot(TM) 64-Bit Server VM (build 1.5.0-beta2-b51, mixed mode)

      java.lang.NullPointerException:
              at test2.main(test2.java:11)

       3) Then launch the same command in 1.4.2_0X on x86 windows machine.

      d;\temp>java -showversion test2
      java version "1.4.2_03"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
      Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)
      null
      java.lang.NullPointerException
              at test2.main(test2.java:11)

       
       The difference is the line after version information.
       The result in 1.5b51 is "space"(or no output), but the result in 1.4.2_03
       is String, "null".


      CONFIGURATION;
       - Itenium2 machine ( above 2) )
         OS : Windows Server 2003
         MPU : Itenium2 900[MHz]
         JRE : 1.5-beta-b51

       - Another machine for jre x86 ( above 3) )
         OS : Windows XP (SP1, Japanese)
         MPU : Pentium IV (1.4[GHz])
         JRE : 1.4.2_03



      NOTE:
        - When the command is launched in 1.5b51(for ia64) with -Xcomp,
          the output message is the same to that in 1.4.2_03.
          The interpreter in 1.5 seems different from 1.4.2.

        - Ttest2.java prints out the result of getMessage()
          in System.out.println() on NullPointerException.
          I attachedt the similar program(test1.java) to the test2.java.
          The test1.java does not cause the above-mentioned diff.
          The message is the same in 1.5-beta-b51 and 1.4.2_03 witj test1.java.
          Only the above test2.java causes the diff.

          
      ::::::::::::::
      test1.java
      ::::::::::::::
      import java.io.*;
      import java.util.*;

      public class test1 {
          public static void main(String[] args) {

              try{
                  String test = null;
                  test.equalsIgnoreCase("Apple");
              }catch(Throwable ne) {
                  System.out.println(ne.getMessage());
                  ne.printStackTrace();
              }
          }
      }
