Under what circumstances JNI_CreateJavaVM will return 0

Question

Hello all,
Can any one please tell me "under what cicumstances JNI_CreateJavaVM returns 0" ?
The following code segment returns 0.
when I try to debug the code segment using VC++ 6.0. jdk 1.4.1 ON WINDOWS 2000 Prof. The debugger first shows status = -1 but once JNI_CreateJavaVM is executed the status changes to 0.
// ----- code segment ----------------
JavaVMOption options[3];
JavaVMInitArgs vm_args;
JavaVM *jvm;
JNIEnv *env;
options[0].optionString = "-Djava.compiler=NONE";
options[1].optionString = "-Djava.class.path=CLASSPATH";
options[2].optionString = "-verbose:jni";
vm_args.version=JNI_VERSION_1_4;
vm_args.options = options;
vm_args.nOptions = 3;
vm_args.ignoreUnrecognized = JNI_FALSE;
int status = -1;
status = (jint)JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
if (status < 0)
printf("\nERROR : Creating JVM with status : %d.\n");
else if (status == JNI_ERR)
     printf("\nERROR : Creating Java Virtual Machine (JVM).\n");
else if (status == 0)
printf("\nJVM status is 0.\n\n");
else
printf("\nVM is created.");
Please help I could not get any clue.
Thanks.
