Jdeveloper 12.2.1.4 Java Version 【2026 Release】

To run JDeveloper 12.2.1.4, your system must meet the following requirements:

If you have multiple JDKs installed on your machine, it’s wise to force JDeveloper to use JDK 8 regardless of system PATH . Edit the jdev.conf file located in jdeveloper\jdev\bin\ : jdeveloper 12.2.1.4 java version

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_202 export PATH=$JAVA_HOME/bin:$PATH To run JDeveloper 12

A: No. Oracle’s official stance is that JDeveloper 12.2.x.x is tied to Java 8. For Java 11 support, you must upgrade to JDeveloper 12.2.1.5.0? Actually, even JDeveloper 12.2.1.5.0 still requires Java 8. The next major version, JDeveloper 14.1.1 (released 2023), supports Java 11 and 17. For Java 11 support, you must upgrade to JDeveloper 12

Note: macOS users on Apple Silicon (M1/M2) must use Rosetta 2 mode, as JDK 8 is x64-only.

This flexibility means you can write Java 8 code (lambdas, streams, new date API) but still generate Java 7 bytecode if needed.
