Type resolution issue lead to false positive depending on the runtime JRE

Run Eclipse with a JDK 8.

Create a Java project targeting a JDK 13, with this code snippet:

class TooManyRootsException extends java.lang.RuntimeException {
  public TooManyRootsException(String message) {
    super(message);
  }
}
 

Despite the fact the class is extending RuntimeException, the rule java:S2166 is creating an issue: Rename this class to remove "Exception" or correct its inheritance.

For another reproducer with rule java:S1854, see https://community.sonarsource.com/t/sonarlint-wrong-useless-assignment-to-local-variables/24297
