SpringBoot application error

Bug Report

Expected Behaviour

My goal is to obfuscate the springBoot application.
I set the main class in the config.
The process went without errors.
After starting I got the following message.

Actual Behaviour

Exception in thread "main" java.lang.IncompatibleClassChangeError: Method org.springframework.boot.loader.jar.JarFileEntries$Offsets.llIllIlIIIlI(I)Z must be InterfaceMethodref constant

How to reproduce the behaviour

Config in attach

Possible fix

obf.txt

Got the same error here. Happens if spring boot version is upgraded to version 2.5.5 and higher. (Offsets in JarFileEntires was introduced).

My fix was to exclude everything in the org.springframework.boot.loader package from the obfuscation.
