执行任何 IO/流时 C++ JNI 崩溃/挂起

2022-01-25 00:00:00 c++ java java-native-interface

在尝试编译 C++ 代码以在 JAVA 端使用时,我似乎遇到了一个大问题.当我尝试做任何与 IO/Stream/Manipulation 相关的事情时,JVM 似乎崩溃了.

I seem to have a big problem when trying to compile C++ code to use on the JAVA side. When I try to do anything IO/Stream/Manipulation related, the JVM seems to crash.

有时,就像我每 10 次运行应用程序时一样,JNI 100% 地处理所有 IO 内容.然后其他时间 JVM 崩溃或挂起.

Sometimes, like once every 10 times when I run the application, the JNI works 100% with all the IO stuff. Then the rest of the times the JVM crashes or hangs.

我正在使用:Windows 10 x64、JAVA jdk1.8.0_102、Netbeans 8.1、g++,其他选项:-D__int64=int64_t

当我这样做时,JNI 工作正常:

When I do these, the JNI works fine:

JNIEXPORT jstring JNICALL Java_Main_nativePrint
  (JNIEnv *env, jobject)
{
    return env->NewStringUTF("HELLO");
}

JNIEXPORT jstring JNICALL Java_Main_nativePrint
  (JNIEnv *env, jobject)
{
    double var = std::sqrt(100);
    return env->NewStringUTF("HELLO");
}

当我尝试合并诸如 printfstd::stringstreamsprintfcoutputs,JVM 崩溃.即使实例化 std::stringstream 似乎让我崩溃.我假设其他类型的操作函数也会让我崩溃:

When I try incorporating anything such as printf, std::stringstream, sprintf, cout, or puts, the JVM crashes. Even instantiating the std::stringstream seems to crash me. I assume other sorts of manipulation function also crashes me:

Java_Main_nativePrint(JNIEnv *env, jobject instance)
{
    int variable = 100;
    char str[15];

    //CRASHES ON HERE
    sprintf(str, "%d", variable);
    //CRASHES ON HERE IF ABOVE COMMENTED OUT OR USING ANOTHER CHAR ARRAY.
    puts(str); //CRASHES ON HERE

    return env->NewStringUTF(str);
}

JNIEXPORT jstring JNICALL Java_Main_nativePrint
  (JNIEnv *env, jobject)
{
    double res = std::sqrt(100);

    //CRASHES HERE ON INSTANTATION OF stringstream
    std::stringstream ss;
    //ss << std::sqrt(100);
    //const char* str = ss.str().c_str();

    return env->NewStringUTF("HELLO");
}

我似乎和这个人有类似的问题:

I seem to be having a similar problem to this person:

使用 c++ 的 JNI 在 cout 上不断崩溃, printf 和方法调用

这是我的转储:

推荐答案

@RustyX 可能是正确的.在一个进程中混合多个 C++ 运行时库不太可能很好,如果有的话.

@RustyX is likely correct. Mixing multiple C++ run-time libraries in a single process is not likely to work well, if at all.

JVM 似乎依赖于 Microsoft C++ 运行时.添加 GNU C++ 运行时不太可能起作用.MinGW 的这个页面解决了一些问题:

The JVM appears to rely on the Microsoft C++ run-time. Adding the GNU C++ run-time isn't likely to work. This page from MinGW addresses some of the issues:

不同编译器品牌创建的库的互操作性

...

尽管 GNU g++ 现在可以链接 MSVC C++ 库,并且可以生成MSVC++ 兼容库/DLL,这并不意味着它们将是由于 C++ 的动态特性,能够在运行时工作.一些可能的原因是:

Even though GNU g++ can link MSVC C++ libraries now, and can produce MSVC++ compatible libraries/DLLs, this does not mean that they will be able to work at run-time due to the dynamic nature of C++. Some possible reasons for this are:

  • 使用显式 .def 文件可以规避的简单名称修改问题.
  • 需要正确编译器选项(-mms-bitfields,...)的不同结构对齐问题.
  • 底层异常和内存模型的根本冲突:
    • MSVC DLL 中的 new/delete 或 malloc/free 不会与 Cygwin newlib new/delete 或 malloc/free 协作.无法释放空间它是使用不同的 new/malloc 在函数中分配的.
    • 由 MSVC DLL 引发的异常不会被 Cygwin 可执行文件捕获,反之亦然.
    • 慢速 GNU SJLJ 异常模型(用于 GCC-3.x 及更早版本)与 MSVC++ 模型兼容,但新的 DWARF2 模型(其中将被 GCC-4.x 使用),将不兼容.

    正在解决不同 new/deletemalloc/free 实现之间的内存管理兼容性问题和冲突即使不是不可能也很难.

    Resolving memory management compatibility issues and conflicts between different new/delete and malloc/free implementations is going to be difficult if not impossible.
