EXCEPTION_ACCESS_VIOLATION in Java

Question

I may have come across a weird bug in Java. When I'm running the following code, I get "EXCEPTION_ACCESS_VIOLATION" exception.

I know the code doesn't make sense (in terms of logic) because it's a subset of the code I originally wrote. If I remove several lines the bug disappear.

Can anyone figure out what's the cause of this bug?

public static void main(String[] args) {
    for (int i=0; i < 4000; i++) {
        System.out.println("item " + i);
        test1();
    }

    //runBatch();   
    System.out.println("Done! bye bye..");
}

public static int test1() {
    int     count;
    int     allMiddleCount;
    int[]   b = new int[0];

    allMiddleCount  = 0;
    for (int i = 1; i < 64; i++)
    {
        // evaluating the size of the subset
        count = 0;
        for (int j = 0; j < 6; j++)
            count++;

        allMiddleCount++;
    }

    for (int i=0; i < allMiddleCount; i++) {

    }

    return 0;
}

Just tested the code you posted and it works fine on my machine (1.7.0_03). What version of Java are you using? — assylias

If you manage to reduce the code leading to the crash, this could be interesting. — Denys Séguret

If the process is dying rather than it being a normal Java exception, it's basically a JVM bug. You haven't said which platform you're on or which version you're using, but try updating to a later version.

Googling for EXCEPTION_ACCESS_VIOLATION lands me on the Oracle site that there are some bugs with the that JVM that are still under investigation

I had this exception while using java to run some specific dlls in my project and it was solved after some months investigating all of our environment, If anyone still needs it here is the link. EXCEPTION_ACCESS_VIOLATION in Jacob dll using VM in Jenkins pipeline

There we have the description of all the things we have tried and maybe it will be of use. The problem was solved by going back to not only the java version, but the specific build version. (in our case it was java 8 build 141)

I tested your code; works fine.

My guess is, this is caused by hardware or software platform problems.
