Oracle JDeveloper 12.2.1.4 is a widely used Integrated Development Environment (IDE) for building service-oriented applications, ADF components, and Oracle Fusion Middleware extensions. Ensuring the correct Java Development Kit (JDK) version is configured is critical for the stability, performance, and security of your development environment.
Point your JAVA_HOME environment variable to the JDK 8 installation directory .
Oracle JDeveloper 12.2.1.4 relies on strict baseline requirements to prevent compile-time crashes and visual designer glitches. Certified Specification / Version Oracle JDK 1.8.0_191+ (JDK 8u211 or newer recommended) Maximum Java Version Strictly less than Java 1.9 (Java 9) Runtime Target Architecture 64-bit JVM only Bundled Application Server Oracle WebLogic Server 12.2.1.4 Alternative Server GlassFish 4.1 (For ADF Essentials) Certified Database Targets
: For production development and Oracle support eligibility, always use the certified Oracle JDK 8 version. jdeveloper 12.2.1.4 java version
While it might launch, you may encounter bugs, performance issues, or failures during application deployment to WebLogic Server. Using 8u211 or higher is highly recommended.

During installation, the installer will prompt you to provide the path to your JDK folder (e.g., C:\Program Files\Java\jdk1.8.0_301 ).
The Java ecosystem now releases new versions every six months, making it impractical for IDEs to support every new version immediately. However, Oracle has committed to supporting LTS Java versions in future JDeveloper releases. Using 8u211 or higher is highly recommended
While not officially supported, some developers have found success running JDeveloper 12.2.1.4 with a later JDK (such as Java 11) for the IDE itself. This requires careful configuration of the jdev.conf file to point to the Java 11 installation. However, a critical caveat applies:
If you need to update the JDK later, edit the jdev.conf file and update the SetJavaHome property . 📦 Distribution Types JDeveloper 12.2.1.4 is available in two main distributions:
Consistency is key. Ensure that both your development environment (JDeveloper) and the deployment environment (WebLogic) are configured to run using JDK 8.
