Starting with Infogix ER v9.3, "ER client" is provided as an alternative to the classic "rich client" option. This was introduced due to changes with Oracle Java. The new ER client is certified / packaged with both Amazon Corretto and IcedTea-Web, more info within Differences between the old and new ER rich client.
Upgrading to Java 11 is currently on the roadmap for ER 9.4, which will run on Amazon Corretto 11. In theory, the rich client may work with Oracle Java 10 or 11, but will not work on Oracle Java 8.
In addition, JavaFX will become required for the optional ER communication module. Oracle Java 11 removed JavaFX; however, Amazon Corretto 11 has JavaFX integrated into it. Unless JavaFX is available in your system, Oracle Java 11 with the optional ER communication module would not work.
