反编译时出错 java class: ItemCollectionInvalidIndex: constants: requested 15873, limit 63

Question

我正在反编译 java 应用程序，我已经完成了 99% .class 文件。但是，我有几个问题：反编译时出错（错误是同一类型）。示例：

南河三： java.lang.IllegalArgumentException: Argument 'index' must be in the range [0, 63], but value was: 15873...

CFR:

Can not load the class specified:
org.benf.cfr.reader.util.CannotLoadClassException: Modules_4.class - java.lang.IndexOutOfBoundsException: Constant pool has 62 entries - attempted to access entry #30318

JDCore: returns 空

Jadx:

ERROR - jadx error: Error load file: Modules_4.class

蕨花：

Job Output:

JAD:

Parsing Modules_4.class...The class file version is 50.0 (only 45.3, 46.0 and 47.0 are supported)
ItemCollectionInvalidIndex: constants: requested 15873, limit 63

download .class file

怎么了？

Answer 1

我之前提到的所有反编译器都没有问题。

这是一个 constant_pool_count 问题。它的发生是因为一些 JPHP decompiler 抵消问题。因此，如果您尝试逆向 jphp 应用程序，请使用您自己的软件将 .phb 删除到 .class 块，每个块之前有几个字节
