Hibernate ORM relies on ByteBuddy as the default bytecode provider.

To support JDK 11, ByteBuddy needs to enable some experimental features and we need an environment variable set: {{ -Dnet.bytebuddy.experimental=true}}.

I discussed with James P. and we decided the best was to include a new line in standalone.conf.

PR to come.

Note: this is needed for WF 14.
