False positive java:S110 with JavaFx

[BillM (Martin Biller)]

• What language is this for?
  • Java
• Which rule?
  • java:S110
• Why do you believe it’s a false-positive?
  • Inheriting from a JavaFX framework layout class shouldn’t trigger too deep inheritance tree warning
  • There are several exceptions to the rule (according to Java static code analysis: Inheritance tree of classes should not be too deep) including javax.swing, but javafx package is not one of them
• I’m using SonarLint
  • in Intellij IDEA 2023.1.2 Build #IU-231.9011.34
  • SonarLint plugin version is 8.3.0.71062 (current as of writing)
  • not connected to SonarQube nor SonarCloud
• How can we reproduce the problem?

import javafx.scene.layout.BorderPane;

public class ExampleClass extends BorderPane {

}

ExampleClass here raises Major Code Smell java:S110 for inheriting from javafx.scene.layout.BorderPane.
Same warning is shown for many other JavaFX layouts including HBox, Label, TextField, etc.

Hey Martin, welcome to our community!

I think it’s reasonable to consider this library another exception to the rule, I created a ticket to fix this.
Thank you for the report!
