It's not really clear to me how to answer these question without more context.
How did you go about making these calculations? What span of time does your analysis concern? What are you counting as technical debt (anything that SonarQube claims is "technical debt")? Are you comparing Jena to other projects with a similar lifespan? Are you comparing Jena to projects that have a similar contribution history? etc. etc.

Dear developers, I am a PhD student in the university of Groningen and the topic of my PhD is the evolution of Technical Debt (TD) in open-source development. I have analyzed some projects from the Apache Foundation (using SonarQube) and I realized that your project has a tremendous number (405,700) of fixed issues, when we compare it to other projects from Apache. I would like to ask you the following 3 questions: 1. Why had been introduced so many issues of TD into your project? 2. The fixing of those issues was in purpose or a coincidence? 3. Do you use SonarQube (or SonarLint) in order to detect and fix the issues? Thank you in advance! With kind regards, George Digkas
