CLOUD-2868 OpenJDK 11 RHEL8 image + CLOUD-2867 OpenJDK 8/RHEL 8

[jmtd]

https://issues.jboss.org/browse/CLOUD-2868

This depends upon the following changes made to cct_module:

jboss-openshift/cct_module#335

[jmtd]

Problems to fix:

• the image contains OpenJDK 8 too
• failing tests:
  • features/image/java/java_s2i.feature:9 Check incremental builds cache .m2
  • features/image/java/java_s2i.feature:309 Check java perf dir owned by jboss (CLOUD-2070)
• "/usr/local/s2i/run: line 15: /opt/jboss/container/maven/default//scl-enable-maven: No such file or directory"

[jmtd]

The perf dir check, at least, is failing because "spring-boot-sample-simple" from https://github.com/jboss-openshift/openshift-examples is terminating shortly after start-up:

Is jolokia the problem here?

Is jolokia the problem here?

No, disabling it with AB_JOLOKIA_OFF does not fix.

Possibly just this version of spring boot does not work with JDK 11?

The perf thing is (at least) jboss-openshift/openshift-examples#38
