Production-ready. | | JDK 8 (8u211 to 8u351) | Yes (Mostly) | Mostly functional, but some older ADF features may experience security-related warnings due to stricter manifest checking. | | JDK 8 (8u352+) | Yes (Caution) | May work but not officially certified after Oracle changed update licensing. OpenJDK 8 builds (e.g., Adoptium) are safer for late updates. | | JDK 9, 10 | No | Module system breaks JDeveloper startup. Even with --permit-illegal-access , the IDE will crash. | | JDK 11 LTS | No | ADF wizards fail. JAXB is missing (JDK 11 removed java.xml.bind). You will see ClassNotFoundException: javax.xml.bind.JAXBContext . | | JDK 17 LTS | No | Even more aggressive module encapsulation. JDeveloper will not launch. | | JDK 21 LTS | No | No chance.
