IMHO this hint should not be needed, a PU referencing a java:comp or java:module datasource is already a hint that the PU will need a resource bound by another component bundled in same jar/war.

By the way I’m not really a fan of using java:comp in a PU, it sets an dependency on a EE component, and that doesn’t seem right. Wouldn't be preferable to use the original java:jboss/datasources/ExampleDS JNDI name, or use an ear and define a java:app bind  at application.xml, to be shared by all modules and components?
