35 * {@link DeploymentUnitProcessor} responsible for setting the default ear subdeployments isolation for each .ear
36 * deployment unit. The default is picked up from the EE subsystem and set on the {@link ModuleSpecification} of the deployment unit.
37 * Unless, the specific deployment unit overrides the isolation via jboss-deployment-structure.xml, this
38 * default value will be used to setup isolation of the subdeployments within a .ear.
