      Description

      - JDK now fully support 64-bit with the new jdk version 1.4.1 with option -d64
      - JDK has changed the definition of jinit from 1.1.8 than 1.2.2 onwards

      JDK sizeof(jint)
                         32bit 64bit
      ------ ------- --------
      1.1.8 long long
      1.2.2 int32_t int32_t
      1.3.1_02 int long
      1.4.1_06 int int

      - This wasn't noticable before jdk 1.4.1 as the 64 option wasn't exist, there was just 32-bit option
      - When compiling using the default, the behaviour using jdk 1.4.1 is the same as 118, 1.2.2, 1.3.1
      - When compiling using -d64 the problem occurs.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        To prove this problem, test the file provided below against jdk 1.1.8, 1.2.2, 1.3.1, and 1.4.1


      files to be used
      ============
      file: test.c

      #include <jni.h>

      int main (void)
      {
      int i =500000;
      fprintf (stdout, "sizeof (jint): %d\n", sizeof (jint));
      fflush (stdout);
      printf("i = %l\n",i);

      return 0;
      }
      ------------------------------------------------

      file: jdk.118 to set the environemt to jdk 118
      -------------------
      setenv JAVA_HOME /usr/java_1.1.8
      setenv PATH $JAVA_HOME/bin/:${PATH}
      -------------------------------------------------

      file: jdk.140
      ---------------
      setenv JAVA_HOME /usr/j2sdk1.4.0_01
      setenv PATH $JAVA_HOME/bin/:${PATH}

      file cc.sh
      ------------

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Expected jint has the same size in all jdk versions.
      ACTUAL -
      ----------------------------
      testing jdk 1.1.8
      ---------------------
      $source jdk.118
      sh -x cc.sh
      ./test

      test result
      ---------------
      sizeof (jint): 8


      testing jdk140
      -------------------
      $source jdk.140
      sh -x cc.sh
      ./test

      test result
      --------------
      sizeof (jint): 4

      REPRODUCIBILITY :
      This bug can be reproduced always.
