Stack overflow in JNI call

Question

Hi,
I am doing a wrapper with JNI for a Windows library of image compression. I have a test program running correctly in C. This program compress data and it can move a lot of memory. If I call this program from a JNI functions I obtain a JNI error:
An unrecoverable stack overflow has occurred.
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_STACK_OVERFLOW (0xc00000fd) occurred at PC=0x5FF88497
Function=unpack_data+0x189D7
Library=C:\WINDOWS\system32\NCSEcw.dll
This error is produce inside my compression library. I try to adjust the parameters (-Xms -Xmx -Xss) of the JVM but in any case before the process ends it shows this exception. I have done other JNI interfaces and I never found with this problem before. Can anybody help me?
Thanks in advance.

I found in this forum a piece of code with a same kind problem but It is simpler than mine. I have proved this program in Windows and it produce the same error. In Linux it runs but if I enlarge the array largebuf it ends with the same error. In Linux I can reserve until 2 MB (in windows +-256K). Is there any way to increase the stack size in a jni call?.
#include <stdio.h>
#include <jni.h>
#include "test.h"
int myprint2(int a, int b){
     char extrabuf[100];
     printf("got here next\n");
     extrabuf;
     return 0;
int myprint(int a, int b){
     char largebuf[260000];
     printf("got here\n");
     myprint2(1,1);
     largebuf;
     return 0;
JNIEXPORT jint JNICALL Java_test_init(JNIEnv *env, jobject obj){
     myprint(1,1);
     return 1;
test.java
public class test{
     public native int init();
     public static void main(String []args){
          new test();
     public test(){
          System.loadLibrary("Nat");
          System.out.println(this.init());
}
