Usage of java 14 record throws java.lang.UnsupportedOperationException: This feature requires ASM8_EXPERIMENTAL

Affects: spring-core 5.2.4.RELEASE

I'm using the java 14 records in my application. Since the upgrade from 5.2.3.RELEASE to 5.2.4.RELEASE, I'm facing this kind of issue when running the application:

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/Users/kleturc/ws_perso/spring-boot-java14-record/target/classes/fr/kevinleturc/java/record/Point.class]; nested exception is java.lang.UnsupportedOperationException: This feature requires ASM8_EXPERIMENTAL

I created a sample project which highlights the issue: https://github.com/kevinleturc/spring-boot-java14-record

Just run command below to get the test failing:

mvn clean install -Dspring-core.version=5.2.4.RELEASE

Culprit seems to be the upgrade of ASM to 7.3.1 (#24438). It makes java record a ASM8_EXPERIMENTAL feature.
