Java Migration in Derry
Java version migrations for Derry organisations, where one boundary is considerably harder than the rest. Moving off Java 8 crosses the introduction of the module system and the tightening of reflective access — so libraries that reached into internals stop working, and those are exactly the libraries that older applications depend on.
Why this comes up
The problem
The application is on Java 8, and two frameworks it depends on rely on reflective access that newer versions no longer permit.
What you get
What we deliver
- The specific boundary identified, since not all version jumps are equivalent
- Dependencies assessed for reflective access and continued maintenance
- Removed APIs found and replaced before the runtime change rather than after
- Build tooling updated, as older versions frequently cannot target newer runtimes
- Performance re-measured, since defaults and collector behaviour have changed
- A long-term support target chosen rather than the newest available release

Java Migration in Derry — common questions
- Why is the Java 8 boundary so much harder?
- Because the platform changed how code may reach into internals. Libraries that relied on that access break, and long-lived applications tend to depend on exactly those libraries — so the work is replacing dependencies rather than adjusting your own code.
- Are later jumps easier?
- Substantially. Once past that boundary, moving between long-term releases is usually a matter of updating dependencies and checking removed APIs — which is why organisations that make the first jump find subsequent upgrades a fraction of the effort.
- Do we need to change build tooling?
- Frequently yes. Older build tools and plugins cannot target newer runtimes, so the build itself becomes part of the migration — and it is worth handling first, because you cannot test anything until it produces an artefact.
- Will performance change?
- Generally for the better, and not identically. Collector defaults and runtime behaviour have moved considerably, so re-measuring after migration is worthwhile — both to capture the improvement and to catch anything that regressed for your particular workload.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
