I have no idea what wrong with this

This project is no longer maintained. You can try changing order of transformers, otherwise you're on your own. Maybe you could also try the stringer version specific transformers (those need to be run using a jdk8), although they should never be mixed with general purpose transformers, see https://github.com/java-deobfuscator/deobfuscator/blob/master/commonerrors/Stringer.md
