C-to-Java 调用通过但 JVM 以一种奇怪/无法解释的方式崩溃

Question

问了第一个问题，所以我会直截了当。

我有一些将与 Java 交互的 C 代码；我做了关于 JNI 和主题的作业。这是代码:

C 部分:

#include <stdio.h>
#include <jni.h>
#include <string.h>

#define CLASSPATH "-Djava.class.path=/scratch/workareas/JTest/Java/" //folder which contains .class files

#define DEBUG 0

JNIEnv* create_vm(JavaVM ** jvm)
{

    JNIEnv *env;
    JavaVMInitArgs vm_args;
    JavaVMOption options;
    strcpy(options.optionString, CLASSPATH); //fix for options.optionString = CLASSPATH;
    if (DEBUG) printf("optionString = %s\n", options.optionString); 
    vm_args.version = JNI_VERSION_1_6; //JDK version. This indicates version 1.6
    vm_args.nOptions = 1;
    vm_args.options = &options;
    vm_args.ignoreUnrecognized = 0;

    int ret = JNI_CreateJavaVM(jvm, (void**) &env, &vm_args);
    if (ret < 0) printf("\n<<<<< Unable to Launch JVM >>>>>\n");
    return env;
}

int main(int argc, char* argv[])
{
    JNIEnv* env;
    JavaVM* jvm;
    printf("Creating JVM....");
    env = create_vm(&jvm);
    printf(" done! [env = %p\tjvm = %p]\n", env, jvm);
    if (env == NULL) return 1;

    jclass myClass = NULL;
    jmethodID dispatchMessage = NULL;
    int counter = 0;

    //Obtaining Class
    myClass = (*env)->FindClass(env, "EventHandler");
    printf("FindClass done! [%p]\n", myClass);

    //Obtaining Method ID
    if (myClass != NULL)
        dispatchMessage = (*env)->GetStaticMethodID(env, myClass, "dispatchEvent", "(I)V");
    else
        printf("Unable to find the requested class\n");

    printf("Calling dispatchEvent() [%p] ...\n", dispatchMessage);
    if (dispatchMessage != NULL)
    {
//      jstring newMessage = (*env)->NewStringUTF(env, "Test call::Called from C\n");
        for(counter = 0; counter < 10; counter ++)
        {
            jint newMessage = counter;
            (*env)->CallStaticVoidMethod(env, myClass, dispatchMessage, newMessage);
        }
    } printf("dispatchMessage() done!\n");

    //Release resources.
    printf("Releasing resources...");
    (*jvm)->DestroyJavaVM(jvm);
    printf(" done! Exiting.\n");
    return 0;
}

Java 部分:

public class EventHandler
{
    public static final int EVENT_CODE_E1 = 1;
    public static final int EVENT_CODE_E2 = 2;
    //...
    public static final int EVENT_CODE_E10 = 10;

    private static EventHandler instance = new EventHandler();


    public EventHandler()
    {
        //TODO: create object here
    }

    public static EventHandler getInstance()
    {
        if(instance == null)
            instance = new EventHandler();
        return instance;
    }

    public static void dispatchEvent(int eventCode)
    {
        switch(eventCode)
        {
            case EVENT_CODE_E1:
                System.out.println("Event 1 firing!");
                getInstance().onEventE1();
                break;
            case EVENT_CODE_E2:
                System.out.println("Event 2 just fired!");
                break;
            //case
            default:
                System.out.println("Unknown event with ID: "+eventCode+" triggered!");
                break;
        }
    }

    private void onEventE1()
    {
        System.out.println("heyoooo");
    }
}

现在问题来了:执行调用 10 次后，这是我得到的输出:

Creating JVM.... done! [env = 0x80e6d20 jvm = 0x177e6a4]
FindClass done! [0x80e7c78]

我不知道是什么原因导致了这次崩溃。我查看了日志，没有任何意义。有人愿意帮忙吗？ :)

编辑:我还附上了日志，以防有人发现有趣的东西。我尝试将它与 JNITest 的 objdump 交叉引用，并尝试使用 addr2line，但它没有给我任何好处。 GDB session 在确定根本原因方面也无效。

问题已经解决。

再搜索一番后，我找到了这篇文章http://docs.oracle.com/javase/1.4.2/docs/guide/jni/jni-12.html#JNI_OnLoad

在它的底部附近是一个很好的例子，说明了如何传递多个选项以及如何命名它们。原来 -Xcheck:jni 作为 -DXcheck:jni 传递(jni:pedantic 也有效)，在我将 strcpy 从我的代码中移出后，我最后不再得到故障转储。我怀疑罪魁祸首是 strcpy，但其中一个成功了。

这是更新后的代码位:

JNIEnv* create_vm(JavaVM ** jvm)
{

    JNIEnv *env;
    JavaVMInitArgs vm_args;
    JavaVMOption options[2];
    options[0].optionString = CLASSPATH; //"-Djava.class.path=/scratch/workareas/JTest/Java/"
    options[1].optionString = "-DXcheck:jni:pedantic";
    vm_args.version = JNI_VERSION_1_6; //JDK version. This indicates version 1.6
    vm_args.nOptions = 2;
    vm_args.options = options;
    vm_args.ignoreUnrecognized = JNI_TRUE; //drop unrecognized options

    int ret = JNI_CreateJavaVM(jvm, (void**) &env, &vm_args);
    if (ret < 0) printf("\n<<<<< Unable to Launch JVM >>>>>\n");
    return env;
}
