> As discussed on wildfly-dev mailing list, to enable the use of multi-release wildfly modules, we will:
>  * Require JDK 11 to compile (for all modules except testsuite modules)
>  ** Adjust compiler flags to use --release=8
>  *** This is equivalent to: -source N -target N -bootclasspath <bootclasspath-from-N>
>  * To ensure surefire tests are run against each supported JRE (wherever necessary), we will update the CI server maven settings to specify system properties for:
>  ** java8.home
>  ** java11.home
>  * Update JDK8 specific CI servers to build with JDK 11, but run integration tests using Java 8.
