Inspectopedia 2026.1 Help

Remove redundant open modifier

Reports usages of open modifier for Spring framework classes.

Instead of having open modifier for class explicitly in the code, it is recommended to use kotlin-spring compiler plugin and omit that modifier.

kotlin-spring compiler plugin generates an additional zero-argument constructor for classes with a specific annotation.
