Hi Martin, We had a long thread on this in January. I'm including below the last message of Ed on this issue.

I guess I am missing why this is so controversial. I brought this issue to the Sun JavaEE Architecture meeting on Tuesday 19 January 2010. This meeting happens mostly weekly and is where the Sun EE Spec leads coordinate efforts to drive JavaEE spec efforts to completion. The technical leadership at this meeting includes Bill Shannon, Sun Distinguised Engineer and past JavaEE spec lead, and Roberto Chinnici JavaEE 6 spec lead. I brought up two issues regarding ProjectStage 1. revive the drive to expose ProjectStage to lower level technologies in EE. 2. have a System property to set the ProjectStage. For 1), the following questions were raised: * What specific use-cases exist for having ProjectStage at the servlet level? If the Servlet EG reviewed the proposal and ultimately rejected it, why bring it up again? * What about Gavin King's "alternatives" proposal? Pete Muir has clarified at this meeting that the "alternatives" proposal from Gavin did not make it into CDI in such a way as to be appropriate for our needs in the ProjectStage feature. For 2), the following points were raised: * There are no other System Properties in all of EE. Why do we need one now? * Why, specifically, does this system property need to be a part of the portable programming model? I voiced that it's useful in cases like mvn jetty run, or mvn tomcat run. Bill countered that such usages are already container specific, so it would best be addressed with a container specific configuration. In conclusion, I think we should close this spec issue and handle the System Property at the impl level. I have opened issue 1539 for this case. I will send a separate email regarding this issue.
