  This paper presents a case study analyzing Hibernate ecosystem software
projects to investigate and demonstrate Code Debt behavior in relation to
severity and rework time. The case study carried out revealed that the Code
Debt with severity related to impact on software maintenance is the most
representative and has the largest rework times to be paid in the Hibernate
ecosystem. Besides, it was found that the distributions of rework times of Code
Debt for all severities undergo variations in the initial versions of the
development.
