执行任何IO / Streams时，C ++ JNI崩溃/挂起(C++ JNI crashes/hangs when doing any IO/Streams)

 在尝试编译要在JAVA端使用的C ++代码时，我似乎遇到了一个大问题。 当我尝试做任何IO / Stream / Manipulation相关的事情时，JVM似乎崩溃了。 
 

 有时，就像我运行应用程序时每10次一样，JNI 100％使用所有IO内容。 然后其余时间JVM崩溃或挂起。 
 

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

 当我这样做时，JNI工作正常： 
 

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printf ， std::stringstream ， sprintf ， cout或puts ，JVM崩溃了。 甚至实例化std::stringstream似乎让我崩溃了。 我假设其他类型的操作函数也让我崩溃： 
 

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");
}

 

 我似乎对这个人有类似的问题： 
 

 带有c ++的JNI不断崩溃cout，printf和方法调用 
 

 这是我的转储：

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.
 

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.
 

I'm using: Windows 10 x64, JAVA jdk1.8.0_102, Netbeans 8.1, g++, additional options: -D__int64=int64_t
 

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");
}

 

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");
}

 

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

JNI with c++ keeps crashing on cout, printf and method calls
 

Here's my dump:

最满意答案

 至少在我的情况下，似乎使用IDENTITY_H的编码实际上阻止了iText嵌入整个字体。 我将编码改为CP1250，一切都按预期工作。 

It appears, at least in my case, that using encoding of IDENTITY_H actually prevented iText from embedding the entire font. I changed encoding to CP1250 and everything worked as expected.
