Local fix

Problem summary

  • USERS AFFECTED:
    Some customers use third party cookie and it can be expected to
    be null sometime and commerce code should handle this situation
    in this particular class
    
    PROBLEM ABSTRACT:
    Null Pointer Exception being thrown when cookie.getValue() is
    null and being passed into URLDecoder in
    RuntimeServletFilter.class
    
    BUSINESS IMPACT:
    Customer is not able to turn on trace because
    RuntimeServletFilter.class will throw null pointer exception
    when cookie is null
    
    RECOMMENDATION:
    

Problem conclusion

  • The NPE should be handled in our code, and if cookie value is
    null, it should be printed as "cookie is null" instead of
    throwing NPE.
