Java运行时环境检测到致命错误：JNI（内部错误）

时间：2014-06-16 12:56:37

标签： vb.net jvm java-native-interface c++-cli

我试图在Java中调用VB DLL方法。我成功地调用了简单的Hello World方法。 现在我尝试调用一个方法，该方法将String作为输入并返回String作为输出。 Wrapper DLL编译成功。但是在运行Java代码时，错误

Java运行时环境检测到致命错误：

内部错误（0xe0434352），pid = 3668，tid = 1124

在搜索时，我发现跟随错误主要是由于本机代码中的错误，我无法弄清楚。

以下是日志文件：

VB代码有一个函数，它接受字符串输入并输出字符串

Public Class Level2Display
    Public Function displayWithParam(str As String) As String
        Return "hello world" + str
    End Function
End Class

这是C ++ / CLI包装器代码

JNIEXPORT jstring JNICALL Java_CsharpConsumer_displayWithParam
(JNIEnv *env, jobject jobj, jstring myStr)
{

         const jchar* temp = (env)->GetStringChars(myStr, null); //Tried changing to JNI_FALSE, still the error persisted. 
        if(temp==NULL)
        {
             return NULL;
        }

        System::String^ managedString = gcnew System::String((const wchar_t*)temp);
        env->ReleaseStringChars(myStr, temp);

        Level2Display^ lds = gcnew Level2Display();    //class in the VB dll
        System::String^ result = (System::String^)lds->displayWithParam(managedString);         //displayWithParam method
        return env->NewStringUTF((const char*)System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi(result).ToPointer());



}

请帮忙！

这条线全都搞砸了。

return env->NewStringUTF((const char*)System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi(result).ToPointer());

你有一个Ansi和UTF-8的错误以及内存泄漏。我建议不要在名称中使用任何Marshal方法HGlobal。 （它们通过执行内存分配和字符集转换违反了单一责任原则，如果您实际使用真实HGLOBAL s）它们会崩溃

相反，请尝试

pin_ptr<const wchar_t> resultChars = PtrToStringChars(result);
return env->NewString(resultChars, result->Length);

答案 1 :(得分：0)

您应该使用GetStringUTFChars而不是GetStringChars。 System :: String是否会生成temp的深层副本？如果没有，请在NewStringUTF之后调用ReleaseStringChars或检查isCopy指针。除此之外，你发布的代码中的一切看起来还不错。
