Hi,
we have a problem with picketlink 2.7.1 after Jboss upgrade.
We update Jboss EAP to 6.4.14 version (from Jboss 6.4.0) and after this we receive an error on start regarding picket link.
After jboss patch we install again the picketlink 2.7.1 as indicated in the picketlink guide.
We use a SAML2AttributeManager class to add a parameter in SAML request.

This is jboss-deployment-structure.xml

<jboss-deployment-structure>
<deployment>
<!-- You must configure the PicketLink dependency to your deployment. The dependency above is a reference to a static module
from JBoss EAP modules directory. -->
<dependencies>
<module name="org.picketlink">
<imports>
<include path="org/picketlink/*"/>
</imports>

Anyone have similar problema?
