With the release of Java 20+, I'm curious if many folks are still running Java 8 servers and what the justification is for sticking with this older version. I've seen discussions around the concept of 'Write Once, Run Anywhere,' where it seems that building on the same JVM is still viable, but mixing in new updates can cause issues. For example, some older applications run perfectly fine on Java 8, but trying to upgrade the JVM results in problems. Given that Java 8 is set to be supported until 2031, is it really a bad idea to continue using it for projects in 2025? What are your thoughts and reasons for maintaining Java 8?

A lot of companies live by the mantra "never change a running system." When things work well, especially in a legacy environment, there's little incentive to invest money in upgrades without a clear return. Plus, there can be significant compatibility issues that arise from updating.
Right, and many companies are just risk-averse. They’d rather keep the old system working than deal with the chaos of an upgrade.
Java 8 does lack critical updates that newer versions have, like improved security and performance features. Also, from a career standpoint, if you want to work with more modern programming techniques, you’re limiting yourself by sticking with Java 8. Many employers prefer candidates familiar with the latest features introduced in newer releases.
Absolutely, security is key! Staying on Java 8 can expose businesses to vulnerabilities, especially if no updates are made.
Yeah, companies will pay for ignorance in security, but it's not a sustainable strategy.
Many teams I know take the 'never touch a running system' approach. If a particular service is performing well and there are no pressing issues, it’s hard to justify the cost of upgrading. At my current job, we have some web services running on old WebSphere servers that can't handle anything newer without expensive migrations.
We face the same problem! Upgrading might break compatibility, and management isn't keen on spending money for a potential headache.
Exactly! Sometimes it's just too complex to weigh the costs and benefits of an upgrade.
In my experience, unless a framework or key libraries explicitly require an upgrade, many businesses stay on Java 8 simply to avoid the costs associated with migration. However, as tech debt accumulates, the longer they wait, the harsher the eventual transition becomes.
True, and once the company signs the contracts, it's nearly impossible to switch without facing legal or financial consequences.
It's a tough call! But all systems need maintenance, and neglecting to upgrade could lead to greater future costs.
Totally! Upgrading can become a massive headache and often ends up being more expensive than it’s worth.
