<br>
Well, I'm talking about Weld SPI and I'm refering to the environment <br>
info provided by the integrator. PAX CDI provides a custom <br>
implementation of org.jboss.weld.bootstrap.api.Environment, which is <br>
fine. The problem is that Weld currently skips registration only if <br>
org.jboss.weld.bootstrap.api.Environments.SE is used.<br>
