Inspectopedia 2025.3 Help

Incompatible with Spring class modifier

Spring component classes could be implicitly subclassed and must not be final. Kotlin class modifiers like enum, data, final and object are effectively final that results to runtime errors.

Example:

@Configuration object MyConfiguration

After the fix is applied:

@Configuration class MyConfiguration
