Which Free Java to Choose in 2019
summary
Oracle stops cost-free production updates after 6 months of free Oracle updates, forcing choices: pay Oracle subscription, stay unpatched (risky), or switch to OpenJDK builds from vendors like AdoptOpenJDK, Amazon Corretto, Azul Zulu, BellSoft, Red Hat or SAP. AdoptOpenJDK publishes binaries across many platforms, runs 20,000 functional tests plus thousands of system and OpenJDK tests and framework checks in public Jenkins pipelines, offers OpenJ9 VM as an alternative runtime and reports 10–20% performance gains for some container and streaming workloads.
