Description

org.apache.maven.project.MavenProject.hashCode() has the following code:

public int hashCode()
    {
        int hash = 17;
        hash = 31 * hash + getGroupId().hashCode();
        hash = 31 * hash + getArtifactId().hashCode();
        hash = 31 * hash + getVersion().hashCode();
        return hash;
    }

if any of those values is null, a NPE is thrown from the method.
