Its more likely that an earlier step (number folding/redundant ifs) was not completely successful. Edit: Also number folding might be not successful because its only executing the first clinit instruction but this obf got multiple.

@Ghost-Kokoro: Make sure to read #653. I will go ahead and remove the links to that JAR archive.

Regarding the exception posted in the OP, it originates from the following:

https://github.com/java-deobfuscator/deobfuscator/blob/ad200d33bc9697851c31dccf442c046b22f8d2c7/src/main/java/com/javadeobfuscator/deobfuscator/transformers/special/SuperblaubeereTransformer.java#L293

To be honest, I am not entirely sure what’s happening here (as I have not inspected the client myself yet), but I think the most likely thing that is happening here is that some processor was run on top of the number pooling.

OK, I will get attention of it next time. Thx.
