Confusion over @NonNullByDefault

[Jeslie Chermak]

CODE FRAGMENT:

import org.eclipse.jdt.annotation.Nullable;

...

    @Nullable

    Point extendPath(final Point point, final int time) {

        ...

        return null;

    }

PRODUCES:

"@NonNull" values should not be set to null(squid:S2637)

@NonNullByDefault was specified for the containing package.

Hello,

Thank you for your feedback. In order to efficiently work on this, we will need a bit more information

• What's your version of SonarLint ?
  
• Are you using connected mode ?
• If yes, what's the version of SonarJava plugin on your SonarQube instance
• What's the fully qualified names of the annotations you are using (including the one from the package)
• Could you provide a self-contained reproducer which would reproduce the case without having to guess the missing parts?

Regards,

Michael

Michael,

I just downloaded SonarLint into Eclipse last week.  I have no SonarQube.  The annotations come from package org.eclipse.jdt.annotation.  I’m in package ai.rideos.robot.routing.  I’ve created a Java package, sonar.bug, which shows this bug and also another (Confusion over @NonNullByDefault) that  I’d filed yesterday.  Here are the two necessary files:

<SquidS2589.java>

THESE ARE SIMPLIFICATIONS of the actual code (extendPath() is normally in another class in the package) which has most of the logic stripped while maintaining the Sonar bug.
