Hi Laird,

thanks for the report. At first glance this looks like you have a fair point there!
While I dig deeper into this, please note that if you need a BM reference within extension, you can get it via parameter injection.
E.g.:

public void afterDeploymentValidation(@Observes final AfterDeploymentValidation event, BeanManager bm) {

    bm.doTheMagicStuff(); // BM will get injected as an observer method parameter

  }
