Cognitive Complexity is a measure of how hard the control flow of a method is to understand. Methods with high Cognitive Complexity will be difficult to maintain.

Generic types shouldn't be used raw (without type parameters) in variable declarations or return values. Doing so bypasses generic type checking, and defers the catch of unsafe code to runtime.

Define a constant instead of duplicating this literal "tagTypeId" 5 times.
Open

                                .setId(jsonObject.optLong("tagTypeId"))

Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.

On the other hand, constants can be referenced from many places, but only need to be updated in a single place.

Noncompliant Code Example

public void run() {

Make "link" transient or serializable.
Open

        private ExceptionLink link;

Fields in a Serializable class must themselves be either Serializable or transient even if the class is never explicitly serialized or deserialized. For instance, under load, most J2EE application frameworks flush objects to disk, and an allegedly Serializable object with non-transient, non-serializable data members could cause program crashes, and open the door to attackers. In general a Serializable class is expected to fulfil its contract and not have an unexpected behaviour when an instance is serialized.

This rule raises an issue on non-Serializable fields, and on collection fields when they are not private (because they could be assigned non-Serializable values externally), and when they are assigned non-Serializable types within the class.

Noncompliant Code Example

public class Address {
  //...
}

public class Person implements Serializable {
  private static final long serialVersionUID = 1905122041950251207L;

  private String name;
  private Address address;  // Noncompliant; Address isn't serializable
}

Compliant Solution

public class Address implements Serializable {
  private static final long serialVersionUID = 2405172041950251807L;
}

public class Person implements Serializable {
  private static final long serialVersionUID = 1905122041950251207L;

  private String name;
  private Address address;
}

Exceptions

The alternative to making all members serializable or transient is to implement special methods which take on the responsibility of properly serializing and de-serializing the object. This rule ignores classes which implement the following methods:

 private void writeObject(java.io.ObjectOutputStream out)
     throws IOException
 private void readObject(java.io.ObjectInputStream in)
     throws IOException, ClassNotFoundException;

A "NullPointerException" could be thrown; "pipelineTaggingFeature" is nullable here.
Open

            fieldMetadataJSON.put("extensible", pipelineTaggingFeature.get("extensibility"));

A reference to null should never be dereferenced/accessed. Doing so will cause a NullPointerException to be thrown. At best, such an exception will cause abrupt program termination. At worst, it could expose debugging information that would be useful to an attacker, or it could allow an attacker to bypass security measures.

Note that when they are present, this rule takes advantage of @CheckForNull and @Nonnull annotations defined in JSR-305 to understand which values are and are not nullable except when @Nonnull is used on the parameter to equals, which by contract should always work with null.

Noncompliant Code Example

@CheckForNull

  stmt.close();   // Noncompliant; stmt could be null if an exception was thrown in the try{} block
  conn.close();  // Noncompliant; conn could be null if an exception was thrown
}
private void merge(@Nonnull Color firstColor, @Nonnull Color secondColor){...}

public  void append(@CheckForNull Color color) {

  if(color == null) {
    System.out.println("Unable to apply color " + color.toString());  // Noncompliant; NullPointerException will be thrown
    return;

Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 60.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

void bar() {
