On a related note to this discussion about EL 3.0 APIs:
http://lists.jboss.org/pipermail/jboss-as7-dev/2013-July/008179.html

See below a previous exchange on an attempt to remove EL 2.2 API dependency from WildFly.

> I created this class to address a fairly major EL performance issue (that factory finder is invoked on every EL invocation, and it is both slow and acquires locks, which cause lots of contention).
>
> We may need to do a similar performance fix in the org.glassfish EL module, but I am not really sure. Assuming the problem still exists and we remove this fix our JSF performance will drop considerably.

>> web/src/main/java/org/jboss/as/web/deployment/ELExpressionFactoryProcessor.java
>>
>> This class is included in the jboss-el-api Specs project API .jar but
>> obviously not part of org.glassfish:javax.el.

>> How do you want to handle this moving forward?  For tests purposes, I created

>> [NOTE:  there are a couple of unrelated changes in that branch]

>>
>> This work was prompted by some signature test failures I was seeing in TCK.
>> The EL 2.2 APIs being in the distribution were unrelated.
