More complex or niche builds may require some code refactor depending on your design principles, but for the most part the runtime environment is similar enough that you won’t notice a difference. Regression testing should be performed, but the migration itself takes only a few steps. If you have modernized your SDLC and established process and infrastructure for effective CI/CD, this really shouldn’t look much different to you than a normal release. If Oracle is brazening enough to have taken this step now, what might they believe they can get away with later down the road?Ī move to OpenJDK or another variant is in most cases an apples-to-apples migration. Not just to avoid exorbitant costs from Oracle, but to free yourself from the grip of a software company who is advertising through this change that they can assert real, financial control of your infrastructure. Justin Reock, chief architect makes his case for migrating, “Begin planning for a move to a GPL variant of Java today. This is important as we are seeing a lot of innovation coming”. The more it is postponed, the more difficult it becomes to adopt the latest version. migrating to newer versions, my recommendation is to also take into account in their analysis the cost of lost opportunity. Giorgos Gaganis, software engineer speaks of the urgency to migrate, “For companies that are currently evaluating getting subscriptions vs. That sort of turnaround is fine for most companies and if you want a warm fuzzy feeling of paying someone to promise they get builds to you quickly, there are companies such as Azul charging a lot less for their OpenJDK support than Oracle is”. OpenJDK is 99% the same code as Oracle JDK (depending on what provider you're getting it from) so what this really boils down to is support.” Consider Your Java Support Needsīrad Wood, architect and developer prompts an important question to consider, “If a CVE comes out tomorrow, how soon do you want to be guaranteed a have a patch available? We just saw this play out a couple weeks ago when providers such as AdoptOpenJDK had builds of OpenJDK 8u202 within days of Oracle's release. Oracle JDK 8 has received what will likely be the last free update and Java 11 was never free so make a plan before you get backed into a corner. If they have to stay with Java SE 8, then I would evaluate which company offers the best value for the money”. Kabutz said, “I would recommend that they move over to OpenJDK 11 as soon as possible. Oracle JDK: Other Considerationsīelow are expert recommendations for companies with production software running on Java SE 8, who have not yet purchased subscriptions. Stuck deciding between OpenJDK and Oracle JDK? Get guidance in this Forrester report.ĭownload Forrester Report OpenJDK vs. OpenJDK can be a good replacement for Oracle JDK in this respect. You can use OpenJDK for commercial software projects. And when combined with enterprise support, OpenJDK performance is top-notch. The OpenJDK builds are becoming more stable with the contributions of the OpenJDK community. Oracle JDK performance used to be better than OpenJDK, but that is changing. OpenJDK's performance is continually improving.
