Book: Getting Started with JBoss EAP for OpenShift Container Platform
Chapter: 1.5. Technology Preview Features

The last paragraph says that "For JDK 11 image streams, the application template is eap73-openjdk11-tx-recovery-s2i.". That is a reference to a template from a different image stream. The reference would make sense in 7.3 documentation, where there are two image streams - one JDK8, one JDK11. But the CD stream is only composed of one JDK, and that is currently JDK11. The sentence can be dropped, as the template eap-cd-tx-recovery-s2i is JDK11 based.

Chapter: 4. Migrating to JBoss EAP CD for OpenShift JDK 11 Image

I think this chapter should not be in the CD documentation at all. It is all about a different image stream. All the templates come from eap73-openjdk11-ubi8 and not from eap-cd template branch.

Chapter: 6.1.2. Deployment

This lists two examples: one that references eap-cd template and claims to be JDK8, the other that references eap73 template and claims to be JDK11. The eap-cd-* is actually JDK11 and the second can be dropped as it references a non-CD stream.

Chapter: 7.9.1. Configuring External Red Hat AMQ Brokers

Similar to above, this showcases two examples. The eap-cd example is correct and JDK11, the second can be dropped.
