Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 61 at org.springframework.asm.ClassReader.<init>ClassReader.java

I have an app that was migrated to Spring Boot 3.1.0 and Java 17. Now I'm trying to make it working together with Spring 6.0.9 (before that, as you may see in the commented dependencies, it had explicitly downgraded Spring version because o history of the versions upgrade.

So, when I try to run bootRun fo rth econfiguration,

I'm getting the below problkem, while the app is on 17th kava, gradle is ran on 17th java and nothing may require the above Java version?

UPD after updating ASM to 9.5 still getting the problem:

You probably are using a too old version of Java ASM.

According to the versions list you need at least version 9.1 to support Java 17.

See answers to this SO question to find out which dependency is using the outdated ASM version: Using Gradle to find dependency tree

I also saw that you are referring to Gradle version 6, this could also be a problem. Please try to update it to a more recent version, since Gradle itself also is using ASM.
The Gradle compatibility chart shows that you need at least version 7.3 to support Java 17
