Capstone 反汇编程序 Java 绑定："Invalid memory access"

Question

我正在使用 Capstone 反汇编程序的 Java bindings。当我运行代码示例

import capstone.Capstone;
import org.junit.Test;

public class DisassemblerTest
{
    private static byte[] CODE = {0x55, 0x48, (byte) 0x8b, 0x05, (byte) 0xb8,
            0x13, 0x00, 0x00};

    @Test
    public void testDisassembler()
    {
        Capstone cs = new Capstone(Capstone.CS_ARCH_X86, Capstone.CS_MODE_64);
        Capstone.CsInsn[] allInsn = cs.disasm(CODE, 0x1000);
        for (Capstone.CsInsn anAllInsn : allInsn)
        {
            System.out.printf("0x%x:\t%s\t%s\n", anAllInsn.address,
                    anAllInsn.mnemonic, anAllInsn.opStr);
        }
    }
}

我得到一个 Error:

我的 maven 依赖项是：

<dependency>
    <groupId>com.github.transcurity</groupId>
    <artifactId>capstone</artifactId>
    <version>LATEST</version> <!-- 3.0.5-rc2 -->
</dependency>

请注意，我在我的项目的根目录中提供了 capstone.dll，它已被找到。否则会收到 UnsatisfiedLinkError。我确保它是最新的 DLL 可用，但它仍然不起作用。够奇怪的，它在 they didn't make an update since July 2018.

之前有效

没关系，it seems to be an issue with a newer JDK。我最近切换到 JDK 11。解决方法是等到 Capstone 支持 Java 9 和更高版本或使用 Java 8 所以确实是一个 Capstone 错误。
