Java Migration in Swansea
Java version migrations for Swansea 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

Working in Swansea
Wales
Swansea combines a large university and health board presence with a coastal tourism economy, and Welsh-language provision is a practical requirement on public-facing work rather than an optional extra.

Java Migration in Swansea — 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 Swansea?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Swansea and the surrounding Swansea area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Swansea businesses do you usually work with?
- Bilingual public-facing systems for institutional clients, and seasonal booking for the Gower tourism trade. Beyond that we work across Higher Education, Healthcare, Manufacturing, Tourism and Public Sector.
- Do you cover the areas around Swansea?
- Yes — we work throughout Wales, including Cardiff, Newport. Swansea is an urban area of roughly 240,000+, and we take on work across the wider Swansea region rather than the city boundary alone.
