奇怪的 Java 异常 java.util.zip.ZipException: 打开 zip 文件时出错

Question

我编写了 JMTI 代理以从应用中获取异常：

#include <jvmti.h>
#include <string.h>

void printStackTrace(JNIEnv* env, jobject exception) {
    jclass throwable_class = (*env).FindClass("java/lang/Throwable");

为什么会出现这个异常？如何解决？

Answer 1

来自Logcat：

java.security.PrivilegedActionException: java.util.zip.ZipException: error in opening zip file

来自文档：

This exception is thrown by doPrivileged(PrivilegedExceptionAction) and doPrivileged(PrivilegedExceptionAction, AccessControlContext context) to indicate that the action being performed threw a checked exception. The exception thrown by the action can be obtained by calling the getException method. In effect, an PrivilegedActionException is a "wrapper" for an exception thrown by a privileged action

检查文件是否未损坏，以及您是否可以访问文件所在的文件夹。

最后，我们使用 getException 获取更多详细信息
