• collections

  - Eclipse Collections ~ Goldman Sachs Collections

• fault injection

  - run setFITCMD; a new CMD class exposed as REST API
    - this will run a java class that will set the global values
    - e.g. List<orig_method: fit_method> will be a globally accessible property
    - this global variable will be used in FIT handler logic
  - create custom fit (fault injection testing) annotations
  - write custom annotation handler that depends on above global variable
    - based on the global values it will call the original method or corresponding faulty method
  - annotate EC classes & methods with these custom annotations
  - run the proper REST CMD exposed at EC now
  - run resetFITCMD; a new CMD class exposed as REST API
    - this will run a java class that will reset the global values
  - the annotation handlers & FIT based CMD classes will be in a new jar 
    - It can be called fit.jar
    - <b> NOTE </b> - this jar will not be shipped in production environment.
    - Absence of jar in JVM will render the annotations & CMD as invalid 
      - without impacting the existing code bases
