Spring-core ASM class reader not working with Java 25 through Spring Boot gradle plugin

As we are migrating to Java 25 with SpringBoot 4.0.6/Spring Framework 7.0.7, we see this stacktrace with mainClass not set in the gradle:

...

Though workaround is available, this looks breaking the Spring Framework Java support promise.
Please triage. Thank you.

As stated on the Spring Boot issue, this definitely looks like a dependency management problem in your application.
Creating multiple issues across projects without a reproducer or more concrete information is just likely to waste our time. Please be more mindful in the future.
