SonarQube Java: Redundant nullcheck with Lombok lazy getter

Hey guys,

I am using SonarQube 9.9.3. I get a possibly false positive with Java:

public final class ModuleTestContext {

    @Getter(lazy = true)
    private static final ModuleTestContext INSTANCE = initialize();

     * Constructor.
    private ModuleTestContext() {

    private void shutdown() {

    private static ModuleTestContext initialize() {
        ModuleTestContext instance = new ModuleTestContext();
        //use shutdown hook to make sure it is executed once at the end of all tests
        Runtime.getRuntime().addShutdownHook(new Thread(instance::shutdown));
        return instance;

Redundant nullcheck of actualValue, which is known to be non-null in ModuleTestContext.getINSTANCE() findbugs:RCN_REDUNDANT_NULLCHECK_OF_NONNULL_VALUE

I am not sure if this might be valid for the Lombok generated code. But I assume Lombok annotations should be ignored in the ruleset?

The upgrade to SonarQube 9.9.3 made the issue appear for us. Before Sonarqube didn’t raise this.


Hey there.

This rule is being raised by GitHub - spotbugs/sonar-findbugs: SpotBugs plugin for SonarQube. You’ll want to reach out to the maintainers of either this plugin or GitHub - findbugsproject/findbugs: The new home of the FindBugs project to report any false-positives.
