<div dir="ltr"><div>What are exactly the rules of making something a sub-spec?</div><div><br></div><div>There have been various examples of this in the past. Reza mentioned JPA, which started as a sub-spec of EJB, even though it was not directly split off from an existing EJB API (you could say it was conceptually a re-imagined EJB Entity Bean, but JPA entities are different enough to stand on their own).</div><div><br></div><div>I wonder what the decisions were at the time to go for a sub-spec, instead of either directly putting it in EJB on the one hand, or going right away for a top-level spec on the other hand.</div><div><br></div><div>Regardless, I think this points out a (practical) weakness in the Java EE umbrella/constituent specs setup. In general we like to split things out into several specs, so that those specs can evolve on their own and are useable by the rest of the platform. E.g. EL is a great example, it's now separate, and can be used everywhere without a dependency on say JSP or JSF.</div><div><br></div><div>But the fact that top level specs need to be individually "active" and must each have assembled their own EG, is a serious process overhead. This is specifically so because with the current Java EE process not all constituent specs are active/open by default for a given spec cycle.</div><br><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Feb 28, 2016 at 8:25 PM, Reza Rahman <span dir="ltr"><<a href="mailto:reza_rahman@lycos.com" target="_blank">reza_rahman@lycos.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><div>I am not so sure "everyone stated" this shouldn't be part of CDI.

Purely from a JCP standpoint, it is possible to have a sub-specification but only if the eventual goal is to spin it out into a separate specification. Examples of this are JPA, interceptors and others. There is no precedent for an "incubator" specification that is somehow optional.

> One of the biggest problems with Concurrency Utilities is, that it started in 2003, then went "dormant" (before the term existed) and was revived to be finalized 10 years later after little or no proper alignment with then state of the art Java EE standards and technologies. It duplicates things, especially in EJB or CDI.<br>

<br>
+1 that pretty much sums it up. Concurrency utils is pretty much broken and unusable as it is today. :/<br>
<br>
Anyway, let’s not fight the past - we need a way forward.<br>
