http://docs.wildfly.org/14/Developer_Guide.html#persistence-unit-properties lists the various WildFly persistence unit hints, some of them, which can prevent runtime bytecode enhancement.  

Some chicken/egg situations:

1.  CDI deployment processing reads application deployment class definitions into memory, if the Hibernate ORM javax.persistence.spi.ClassTransformer is not yet registered at the time that the application class definitions are read by the CDI deployment processor, then runtime bytecode enhancement will not occur.

2. Application deployments that include @DataSourceDefinition and include persistence units that use the application defined datasource, will need to bootstrap the persistence unit very late (e.g. well after applications class definitions are already read), as the @DataSourceDefinition is not available before application classes have already been read.  These apps might set jboss.as.jpa.classtransformer=false or wildfly.jpa.twophasebootstrap=false (see example unit test [1]).
