allatori.RuleStringDecryptor fails with "IndexOutOfBoundsException: Trying to set an inexistant local variable 0" #753

I was trying to detect the obfuscator of a jar file. My detect.yml file was like this:

input: files name.jar
detect: true

An ordinary detect.yml file. I did the "java -jar deobfuscator.jar --config detect.yml" command, but it threw up bunch of errors, and finally I got a message that told me that deobfuscation failed and I needed to open a ticket with the following error:

java.lang.IndexOutOfBoundsException: Trying to set an inexistant local variable 0

I did everything correct. No typos, no wrong usage, no nothing and I am pretty sure of that. Please reply back ASAP.

Thanks for reporting the problem. I will soon improve the try-catch in the detections.
