I recently joined a new company and was surprised to find we're working with very old Java code—some of it from 20 years ago, using Java 5-7. This means we don't get to take advantage of the newer features that come with more recent versions. Since versions 5-7 are now deprecated according to Oracle, what's stopping us from upgrading? Why are companies hesitant to adopt newer versions? I thought newer versions were supposed to be backward compatible. On the same note, can someone explain why we still have to manage Spring beans when Spring Boot exists? I'm really confused about the whole situation and would love to hear your thoughts.

Fear of the unknown is a major factor here! Companies don't always have sufficient testing in place, so they worry about breaking existing functionality during upgrades. They might also hesitate to push for an upgrade without a clear business case showing the ROI. It's a balancing act between maintaining legacy systems and moving towards modern solutions.
It's not just about the code itself; it often comes down to the infrastructure. If the app servers or other tech stack components haven’t been updated, upgrading Java can become a logistical nightmare. It's easier for companies to keep patching what works than to undertake a risky upgrade that might create new issues.
It's frustrating, for sure! My team is stuck with Java 5, and I feel like I'm working with dinosaur code every day.
Companies often drag their feet on upgrading for a variety of reasons. Some say, 'If it ain't broke, don’t fix it.' There's also pressure from backlogs—updating code might mean less time for new features. Plus, it might not just be about Java; it’s often about dependencies that are no longer maintained or that don't play nice with newer versions. Especially moving to Java 8 can be complicated due to breaking changes in later versions.
I totally get that! It feels like such a trap when everyone just keeps saying it's working fine. But eventually, those old dependencies will bite you back, right?
One of the challenges is the lack of senior developers who know how to tackle these upgrades effectively. Many teams may not have the right expertise or resources, and without someone pushing for change, it's easy to stick with the status quo for too long. It can be a huge risk to suggest completely rewriting an application that seems to be functioning okay.
I can relate! It feels like a long uphill battle to get any traction on these initiatives.
Exactly! And it feels like chasing a moving target when you need to keep up with security patches too.
