Java Runtime Environment/JDK

Oracle Java SE Development Kit (JDK) 1.8 or later.


By default, some MacOS versions are shipped with JDK 1.9, which will not be compatible with WSO2 EI Tooling. Hence, you need to override it by installing Oracle JDK 1.8 and updating the folder path of the JDK 1.8 distribution in the Eclipse distribution.

For example, if you are using MacOS High Sierra (Version 10.13.4) with Oracle JDK 1.8.0_151, add the following properties to the <ECLIPSE_HOME>/Contents/Info.plist file.
