Attempting to use -DallTests -Delytron results in the following error: -

[ERROR] }
[ERROR] Cannot start embedded Host Controller: WFLYEMB0022: Cannot invoke 'start' on embedded process: WFLYHC0097: Domain base directory does not exist: /home/darranl/src/wildfly13/wildfly-core/testsuite/standalone/target/wildfly-core/domain

I believe this is actually caused by WFCORE-3769 which provisions a standalone server only.

We don't currently run -Delytron jobs for WildFly Core but this bug causes problems with experimental builds where we may want to use -Delytron.
