Hi Jan,
Thanks for your contribution, yes this could be done without adding a
dependency.
We could avoid reflection stuff and use byte code exploring. Mojarra 2.0
uses code from Glassfish codebase for this byte code stuff btw. You may take
a look at their implementation to give an idea.
I agree

That sounds great.
What is your general approach? Just read in the class as byte[], then
use the class-file-format rules to get to the annotations sections on
the class and the methods? From my quick scan of the classfile spec it
seemed reasonably easy to do that...
This line is the
I also have some questions for the JSF 2.0 EG, like what classpaths
need to be scanned by default. Or the policy of dealing with runtime
invisible annotations (I can read them, but Reflection cannot). I'm
also interested in general rules regarding class/method signatures.
For example, do you

LOL! Don't worry. I won't copy their codebase. ;-) I already have a
working implementation.
Hi Cagatay,
The issue of what packages to scan is the responsibility of the
specification here however. We cannot simply decide to avoid some packages
in this case, we have to wait for the spec to normalize a way to define
those.

In projects with 3000 classes and 60 jar files you are up to 30 seconds, or
even more, scanning time.

I've checked mojarra 2.0 some time ago to see how do they implemented this,
well they're using reflection/class way.
Spring's scanning mechanism also gives out of memory if you dont specify a
sub package name to scan.
So, my thought is to implement this in myfaces, it's not a complicated task
as
My 2 cents: Don't load classes to use java.lang.reflect on it:
- What if a class does something bad (or just about anything) in a static
initializer?
For example try to run the code below. It will EXIT THE VM
- Can you be sure that those classes are unloaded again?
- Performance: It is

I don't think Scannotation itself is an issue, but it has a required
dependency on Javassist, which has an LGPL license. Isn't that a

Using Scannotation, however, would definitely ease development.

Hi Jan-Kees,
I think it's ok for Apache projects to depend on external libraries that are
not licensed under ASL 2.0. However that would be some extra dependencies
for MyFaces and we try to minimize those. On the other hand the gain might
worth it in this case imho if those libraries are deployed
I think we should avoid scannotation, not that it's bad but because it's a
dependency.
MyFaces already has more dependencies compared to mojarra afaik and
increasing those doesn't sound good.
Classpath scanning is a tricky business and it's good both performance and
computing wise to limit the
