> Perhaps filter out the "org.hibernate.validator"?
I'll try something, but I'm not sure what to try exactly. Looks like adding
NegatingClassFilter for org.hibernate as after-filter isn't the way so I'm not
sure which way to go to block some packages/classes completely regardless their presence
anywhere or not.
There should really be some "fully blocking" approach possible (and simply).
The same negating filter should also work for after phase.
The fully blocking filter is NothingClassFilter.
EDIT: I tried to setup filters on org.hibernate.validator package
several ways - before-filter was always NegatingClassFilter on that package, after-filter
was once NegatingClassFilter, once just PackageClassFilter, also tried
RecursivePackageFilter for both before-filter and after-filter in the end but to no avail.
Hmm, yeah, I think that was a typo on my end, we need RecursivePackageFilter.
But apart from that I don't see what can go wrong.
Could you debug a bit more?
Or do you have some test case / example to share?

The fully blocking filter is NothingClassFilter.
Of course this
only blocks things between domains.
If the resources are locally present, we need diff mechanism to exclude them -
jboss-classloading.xml.

I've found out that if I specify an ear file name as domain name in
jboss-classloading-domain.xml then I see two classloaders in JMX view:
one is
domain:
"jboss.j2ee:extension=LoaderRepository,service=EARDeployment,url='myapp.ear'"
- the default one created by ear deployer, with parent policy:
"AFTER_BUT_JAVA_BEFORE" and parent domain "DefaultDomain"
domain: "myapp.ear" - created from jboss-classloading-domain.xml, with parent
policy: "(before=EXCLUDE [org.hibernate.validator] after=)" and no parent domain
(null).
So it looks like I'll have to either add jboss-classloading.xml to change the domain
name to the same valuse which is in jboss-classloading-domain.xml or modify
jboss-classloading-domain.xml to use the default one.
I quickly tried both but it broke the app - it couldn't load
javax.servlet.http.HttpServlet (using negated recursive package filter for
org.hibernate.validator as before-filter). With some other filter it couldn't start
for other reasons so I'll try figure out a bit more about what actually happens..
Also I noticed that war classloaders don't show up any parent domain (null).
So do you think that NothingClassFilter combined with RecursivePackageFilter (the same way
as NegatingClassFilter) would do the desired blocking?
