Things may have changed, but my impression as of several years ago was that JD-GUI was far, far behind the state of the art (Fernflower, aka the built-in IntelliJ decompiler) in terms of correctness, re-sugaring, support for modern Java features, and so on. Fernflower is open source as part of IntelliJ: https://github.com/fesh0r/fernflower
Is there a good GUI for this a la jadx-gui that isn't an entire IDE?
You've used GPL2 code taken from git (hashmap.c) in your Apache 2.0 project. https://opensource.stackexchange.com/questions/10737/inclusi...
I'm curious, how did you notice this? Do you have a scanner that checks these sorts of things or is it something that you are passionate about?
I don't think it's available in a standalone repo but it IS available as a standalone library, IntelliJ's FernFlower decompiler is the gold standard https://github.com/JetBrains/intellij-community/blob/master/... https://www.jetbrains.com/intellij-repository/releases I guess there's some history there that I'm not familiar with because JBoss also has a FernFlower decompiler library https://mvnrepository.com/artifact/…
Can you also write a C decompiler in pure Java language?

1. How silly to write such a thing in C from scratch. Such a project will invariably invent half of Lisp in order to have the right kind of infrastructure for doing this and that.
2. Let's look for some of it up and down the tree. Oh look, there is a bitset and hashmap, see? I don't see test cases for these anywhere; is it original work from this project or battle-tested code taken from elsewhere?
3. Open hashmap.c ...
GPL violation found in half a minute.

I am writing the part of decompiling dex and apk. The current speed is about 10 times faster than that of Java, and it takes up less resources than Java. And the compiled binary is smaller, only about 300k. Thank you for your attention.
> 10 times faster than that of Java I was hoping that these days' Java would be "almost" as fast C/C++. Oh well.
I am always curious how different C programs decide how to manage memory. In this case there are is a custom string library. Functions returned owned heap-allocated strings. However, I think there's a problem where static strings are used interchangably with heap-allocated strings, such as in the function `string class_simple_name(string full)` ( https://github.com/neocanable/garlic/blob/72357ddbcffdb75641... ) Somet…
static bool is_java_identifier_start(char c)
{
return (isalpha(c) || c == '_' || c == '$');
}
I think some implementations are hardened against this issue, but not all.

By the following very short garden path: 1. How silly to write such a thing in C from scratch. Such a project will invariably invent half of Lisp in order to have the right kind of infrastructure for doing this and that. 2. Let's look for some of it up and down the tree. Oh look, there is a bitset and hashmap, see? I don't see test cases for these anywhere; is it original work from this project or battle-tested code…

I'm not them, but it does straight up say in hashmap.c that the code was copied from https://github.com/git/git/blob/master/hashmap.c , which is under the GPL license.
I cannot help but wonder why starting a new project in C in 2025. It’s like driving a car with no seat belts. You sure you want to do that?
But stupid real-world analogies are stupid.
