Jni 方法在两次调用后导致 JVM 崩溃

Question

好吧，我的问题是我有一个使用 Jni 从 Java 应用程序调用的 C++ 方法。问题是该方法在第一次调用时运行良好，但当第二次调用时，JVM 崩溃了。显示错误：

#

这是使用 Jni 从我的 Java 应用程序调用的 C++ 方法：

JNIEXPORT void JNICALL Java_MainFrame_Jni_Functions_displayParameterResults  (JNIEnv *env, jobject obj){

cout << "begin!!!!!!!!!!!!!!" << endl;

cout << "before!!!!!!!!!!!!!!" << endl;
jclass jclazz = env->FindClass("MainFrame/Jni/TablesObjects");
cout << "after***************" << jclazz <<endl;


int size = xtremeDataGA.resultsData.parameter.size();
jdouble* jdbl = new jdouble(size);
for(int i=0; i<size; i++)
    jdbl[i] = xtremeDataGA.resultsData.parameter.at(i).at(0).at(0);
jdoubleArray jdblArr = env->NewDoubleArray(size);
env->SetDoubleArrayRegion(jdblArr, 0, size, jdbl);


jclass jStringClass   = env->FindClass("java/lang/String"); 
jobjectArray jStringArray = env->NewObjectArray(6, jStringClass, 0);
for(int i=0; i<6; i++)
    env->SetObjectArrayElement(jStringArray, i, env->NewStringUTF("a") );


jmethodID mid = env->GetStaticMethodID(jclazz, "resultsParameterInsertCol", "([Ljava/lang/Object;[D)V");
env->CallStaticVoidMethod(jclazz, mid, jStringArray, jdblArr);

cout << "end!!!!!!!!!!!!!!" << endl;
}

编辑： 问题已解决。没有任何语法/编码错误。该错误是由于我需要在本地重新声明的全局对象声明造成的。
