Inspectopedia 2025.2 Help

Final declaration can't be overridden at runtime

Reports cases when your code prevents a class from being subclassed by some framework (for example, Spring or Hibernate) at runtime.

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

ImplicitSubclassInspection
Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Inheritance issues

Typical examples of necessary but impossible subclassing:

  • final classes marked with framework-specific annotations (for example, Spring @Configuration)

  • final, static or private methods marked with framework-specific annotations (for example, Spring @Transactional)

  • methods marked with framework-specific annotations inside final classes

The list of reported cases depends on the frameworks used.

Suppressing Inspection

You can suppress this inspection by placing the following comment marker before the code fragment where you no longer want messages from this inspection to appear:
