Re: [jboss-as7-dev] Module for EL
Hi,
another related question is which EL implementation to use.
We are currently using JBoss EL which afaiu is not actively maintained anymore. EE 7 will
bring an update to EL via JSR 341. What implementation will we use within AS8? The
reference implementation, an somehow updated JBoss EL or JUEL (provided there will be a
JSR 341compliant JUEL version).
From the Bean Validation perspective and in order to move
https://issues.jboss.org/browse/AS7-6665 along just creating a standalone el module is
enough, but I think for the long term we need to discuss which EL implementation to use.

Thanks to Scott's help, I think I understood the details a bit
more.
HV uses javax.el.ExpressionFactory/FactoryFinder which in turn uses the TCCL to find
implementations and cache it in FactoryFinderFache. For WAR deployments, the cache is
pre-populated by ELExpressionFactoryProcessor with the implementation from the web module
mentioned by Shelly.
As this is not the case for other deployment types (e.g. RARs), tests using HV based on
such deployment types fail with the exception.
So I think a separate EL module (upon which HV could depend, independently from the
current deployment type) would indeed make sense.
