## Install Java 8 SDK

```
## Install Oracle SQL Developer
Before you can use SQL Developer with OpenJDK 8, you need to install JFX. Please note, that Oracle does not officially support OpenJDK, but it does work; however, you need to use JFX version 8. You will have to download the "Other Platform" where the JRE is NOT included with the installation.
