- 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

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.
