[ The systems that were never allowed to stop ]
Java runs a great deal of enterprise infrastructure and a great many older Android apps. Most of our Java work is maintaining, upgrading and gradually modernising systems the business cannot switch off.
Java runs a great deal of enterprise infrastructure and a great many older Android apps. Most of our Java work is maintaining, upgrading and gradually modernising systems the business cannot switch off.
Tell us which Java version you are stuck onWe target LTS releases and plan the hops between them, because an application stranded on Java 8 is accumulating security debt it cannot patch.
Where new Java is genuinely warranted, Spring Boot with sensible defaults rather than a hand-assembled stack nobody else will recognise.
Java Android apps still in the Play Store need target API compliance and security fixes. We keep them shippable and say when Kotlin is worth the move.
A monolith broken up only where there is a reason, one bounded piece at a time, with the old system running throughout.
Keeping business-critical Java running: security patching, dependency updates, bug fixes and the changes the business needs each month.
Java 8 or 11 to a current LTS and Spring 4 or 5 to 6, in staged steps with a regression pass at each rather than one large jump.
Older Java Android apps kept compliant with Play's target API deadlines and secure, with a costed view on whether moving to Kotlin is worth it.
Java version, framework versions, dependency vulnerabilities, build system and how deployment actually happens. Most of these systems have no current documentation.
Java 8 and 11 to a current LTS, in steps, with a regression pass at each. This is usually the highest-value piece of work available.
JUnit around what moves money or data before changing anything. Enterprise Java is exactly where untested refactoring goes badly.
Spring Boot upgrades, configuration out of XML, containers instead of an application server — each shipped separately rather than as one release.
A service pulled out where there is a scaling or ownership argument. Breaking a working monolith without one buys distributed problems.
A runbook, a repeatable deployment and the architecture written down — typically for the first time since the original team left.
Very little of our Java work is greenfield, and that is the honest shape of Java in the market we serve. What arrives instead is a system that has run the business for a decade, sits on Java 8, has dependencies with known vulnerabilities, and cannot be taken offline for a rewrite.
That is not a rewrite candidate. It is a runtime upgrade, a set of tests around the paths that matter, containerisation, and a deployment that does not depend on one person's knowledge. Done in that order it removes most of the risk for a fraction of the cost of replacement.
An application on an unsupported JDK cannot receive security fixes. Everything else waits until that is addressed.
Extraction needs a scaling or ownership reason. Without one you have swapped a working system for a distributed one.
Enterprise Java carries a decade of undocumented rules. Changing it without a safety net is guessing with the business.
With a long-term support release every two years, staying current is scheduled maintenance rather than a crisis every five years — for teams that plan it.
The javax to jakarta package move made the Spring 6 upgrade a real project rather than a version bump, and it is what has stranded many systems on Spring 5.
Project Loom made high-concurrency Java far simpler to write, which is genuinely worth upgrading for on I/O-heavy services.
For enterprise systems that must run for a decade, yes — the tooling, the operational maturity and the hiring pool are all deep. For a new consumer product or a small business application, Laravel or Node will usually get you there faster. We are honest about which situation you are in.
