Java HotSpot Virtual Machine

I'm writing a Window application which has to invoke the JVM. The routine is more or lees like this:

int InvokeJavaVirtualMachine()
{
    char sJRERuntimeLib[512];
    
    HMODULE hModule;
    p_JNI_GetDefaultJavaVMInitArgs p_JNI_GetDefaultJavaVMInitArgs_function;
    p_JNI_CreateJavaVM p_JNI_CreateJavaVM_function;

    JavaVM* javaVM;
    JNIEnv* jniEnv;
    JavaVMInitArgs javaVMInitArgs;
    JavaVMOption javaVMOptions[1];
    jint jintRes;
    jclass jclassString;
    jclass jclassMainClass;
    jmethodID jmethodIDMain;
    jstring jstringMainParameter;
    jobjectArray jobjectArrayArgs;
    
    int iReturnCode = 0;

    if (GetJRERuntimeLib("1.4", sJRERuntimeLib)!=0) {
        iReturnCode = -1;
        goto invokejavavirtualmachine_error;
    }
   
   
    hModule = LoadLibrary(sJRERuntimeLib);
    if (hModule==NULL) {
        iReturnCode = -2;
        goto invokejavavirtualmachine_error;
    }
    
    p_JNI_GetDefaultJavaVMInitArgs_function = (p_JNI_GetDefaultJavaVMInitArgs)GetProcAddress(hModule, "JNI_GetDefaultJavaVMInitArgs");
    if (p_JNI_GetDefaultJavaVMInitArgs_function==NULL) {
        iReturnCode = -3;
        goto invokejavavirtualmachine_error;
    }    
    p_JNI_CreateJavaVM_function = (p_JNI_CreateJavaVM)GetProcAddress(hModule, "JNI_CreateJavaVM");
    if (p_JNI_CreateJavaVM_function==NULL) {
        iReturnCode = -4;
        goto invokejavavirtualmachine_error;
    }    

    javaVMOptions[0].optionString = USER_CLASSPATH;
    javaVMInitArgs.version = JNI_VERSION_1_2;
    javaVMInitArgs.options = javaVMOptions;
    javaVMInitArgs.nOptions = 1;
    javaVMInitArgs.ignoreUnrecognized = JNI_TRUE;
    
    jintRes = (p_JNI_CreateJavaVM_function)(&javaVM, (void**)&jniEnv, &javaVMInitArgs);
    if (jintRes<0) {
        iReturnCode = -5;
        goto invokejavavirtualmachine_error;
    }
    
    jclassMainClass = (*jniEnv)->FindClass(jniEnv, "JApp");
    if (jclassMainClass==NULL) {
        iReturnCode = -6;
        goto invokejavavirtualmachine_error;
    }
    
    jmethodIDMain = (*jniEnv)->GetStaticMethodID(jniEnv, jclassMainClass, "main", "([Ljava/lang/String;)V");
    if (jmethodIDMain == NULL) {
        iReturnCode = -7;
        goto invokejavavirtualmachine_error;
    }
    
    jstringMainParameter = (*jniEnv)->NewStringUTF(jniEnv, " from C!");
    if (jstringMainParameter == NULL) {
        iReturnCode = -8;
        goto invokejavavirtualmachine_error;
    }
    jclassString = (*jniEnv)->FindClass(jniEnv, "java/lang/String");
    if (jclassString==NULL) {
        iReturnCode = -9;
        goto invokejavavirtualmachine_error;
    }
    jobjectArrayArgs = (*jniEnv)->NewObjectArray(jniEnv, 1, jclassString, jstringMainParameter);
    (*jniEnv)->CallStaticVoidMethod(jniEnv, jclassMainClass, jmethodIDMain, jobjectArrayArgs);
    
    invokejavavirtualmachine_error:
        if ((*jniEnv)->ExceptionOccurred(jniEnv)) {
            (*jniEnv)->ExceptionDescribe(jniEnv);
        }
       if (javaVM!=NULL && (*javaVM)!=NULL) (*javaVM)->DestroyJavaVM(javaVM); 
        if (hModule!=NULL) FreeLibrary(hModule);
        
        return iReturnCode;
}

Everything seems to work fine but CallStaticVoidMethod doesn't wait for the Java application to end. It returns inmediately. Is this normal?

Besides when I clic on the close button in the Java application, the Window application whick invoked the Java application is closed too. Is this normal?

Any help would be welcomed. Thanks.
