[NoSuchMethodHandlerException] Hide Access Transformer

[fahrenheit93]

Hello again, i'm opening a new issue because the last one was resolved for the first of two files. The second one : palamodaddons-1.0.0.jar.zip

I logged the different classes here :

classNodes().forEach(classNode ->
    classNode.methods.stream().filter(methodNode -> !methodNode.desc.equals(bootstrapDesc)).forEach(methodNode -> {
            if (DEV) {
                System.out.println("ClassNode Name : " + classNode.name);
                System.out.println("ClassNode File : " + classNode.sourceFile);
            }

From here, i ignore the class causing the NullException, i don't know if it's good or not.

My config file :

The error : com.javadeobfuscator.deobfuscator.executor.exceptions.NoSuchMethodHandlerException: Could not find invoker for palamodaddons/client/on R(I)Ljava/lang/reflect/Method; @ palamodaddons/client/PProxyClient vT(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object; at com.javadeobfuscator.deobfuscator.executor.MethodExecutor.execute(MethodExecutor.java:1359)

It says couldn't find, yes i ignored these ones, if not, it's NullPointerException...

I used StringEncryptionTransformer one time before and it worked. I tried with doing a ClassNormalizer too. I tried doing a ReflectionObfuscationTransformer but java.lang.ArrayIndexOutOfBoundsException at java.lang.reflect.Array.get(Native Method) so..

I you can do it, please tell me how you did it thank you.

P.S : I don't want to ignore so much files, that's useless..

[ThisTestUser]

I gave you the file in the previous issue. You need to use StringEncryptionTransformer and then HideAccessTransformer. You can use this version of HideAccess to skip over unresolved libraries: https://gist.github.com/ThisTestUser/2ff4cad222667353e242214de18913a8

[fahrenheit93]

Thank you @ThisTestUser but this is another mod, the last one was weirdly perfect. I'll try to understand your changes in the transformer.

EDIT : Ok i understand your changes, you catch the exception on each JavaField and continue, i wanted to do that with a try catch bloc wrapping the classNode().forEach but the program didn't write the file at the end :/

But a last question, when i start doing a reflection obfuscation tranformer, it found some, maybe i need to use this one too?

I think of :

Maybe invokedDynamic transformer too

[ThisTestUser]

I did give you the deobfuscated addon jar: https://github.com/java-deobfuscator/deobfuscator/files/3025006/MC-Addon2Deob.zip If you find invokedynamic in the code this means that the transformer skipped over it because it couldn't resolve the library.

[fahrenheit93]

Ok, so how did you do to avoid invokedynamic problems? I'm pretty sure i used same libs that you were using, except Minecraft.jar which may be different a bit.

How did you decompile properly minecraft.jar ? Mine is a bit broken i think (ex: ItemStack)

[ThisTestUser]

You need the forge SRG and regular forge Jar, which are downloaded when you setup a forge workspace.

[fahrenheit93]

BON2 can do it, am I right? I mean, the remapping

Ok I am building a forge workspace

I'm going to search how to use the SRG (This is a mapping file I believe)

[fahrenheit93]

I can't get rid of invokedynamic, i used ForgeGradle, and opened forge/build/tmp/recompSrc and export .jar from there (using Eclipse).

ItemStack can't be resolved, the file you deobfuscated doesn't have any Invokedynamic in, that's curiously pretty good. I would like you to explain me how you did it properly, because I'm pretty sure this is Minecraft.jar dep, like on discord, here is for the Java-Deobfuscator issues, so this is not related anymore now i think : Follow#9407

Thank you, that's a little bit curious, i'm missing something.

[ThisTestUser]

The JARs are here: C:\Users\NAME.gradle\caches\minecraft\net\minecraftforge\forge\1.7.10-VERSION-1.7.10 Attach the SRG Jar, and then the normal jar. If it still doesn't work attach the normal jar and then the srg jar.

[fahrenheit93]

Are you telling me that the order in the "libraries" field (config.yml) is important? I have a lot of dependencies

[ThisTestUser]

Only for the forge jars.

[fahrenheit93]

Ok, so Forge SRG, and the "normal" is that the Universal one?

EDIT : I can take the forge 1.7.10 from the launcher tho

I'll try that, thanks

[ThisTestUser]

Go the folder I told you to go to and you'll find the jars. One is called forgeSrc-....jar, one is forge-...-srg.jar

[fahrenheit93]

SRG is a mapping (naming system) file, am i right btw? Searge i believe from what i found

EDIT : Last but not least : Is Minecraft.jar obligatory? I'll see missing deps tho EDIT : Stupid question, minecraft.jar isn't, so no more Invokedynamic now thank you !

Is that the same way with the first file you were deob ? The biggest one i mean

[ThisTestUser]

Yes, but you will see invokedynamics because there are still missing dependencies.

[fahrenheit93]

I can log some classes which can't be resolved, so from that, we can know what libs are missing, am i right? And if some libs are obfuscated, could it be a problem when resolving these ones?

Example log with your version of HideAccessTransformer : Could not find classnode com.google.gson.Gson

EDIT : Not all classes show the missing libs btw apparently

[ThisTestUser]

You also have to add all 1.7.10 libraries if you want to resolve that. But even then you'll still encounter missing dependencies, which you can't solve.

[fahrenheit93]

Is there a way to know exactly what lib is missing? Because invokedynamic(-33hvc0:(Ljava/lang/Object;)Ljava/lang/String Is not so obvious. This is from the Java jar i believe, which is already in the "path" field (config.yml)

[ThisTestUser]

If you added all the libraries I told you to, there's nothing else you can do. But if you wanted to look at all the libraries, you can just use StringEncryptionTransformer and look for the HideAccess class to find out which classes are referenced.

[fahrenheit93]

Ok you were really helpful thank you, i understand a bit more, i'll study that more further that's interesting.
