Going through Upgrade documentation for AE/ARA v10/v5 -> v11.2.2.
On compatibility checker requirements for ECC and AE for Java state v 1.8 Is this hard requirement to have Java 1.8 installed or v11.2.2 can still run on Java 1.7?
On our compatibility checker it stated that Automation Engine 11.2.2 needs Oracle Java 1.8.
The compatibility with Java 1.7 can work but in case of behaviour/bugs/issues you will be required to move to Java 1.8
So we recommend to upgrade your Java to 1.8 version.
