Hello,

I am trying to setup the CAS Management webapp 6.2.2 with CAS Server 6.2.5. 
but I am running into the following issue : 

When I log in the CAS Management webapp with a user that exists in the 
users.json file of the Management webapp, the authentication with CAS is 
successfull but I get the message "Management app is not available" in the 
GUI and in the cas-management.log file, I get the error: 

ERROR 
[org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/cas-management].[dispatcherServlet]]
 
- <Servlet.service() for servlet [dispatcherServlet] in context with path 
[/cas-management] threw exception [Handler dispatch failed; nested 
exception is java.lang.NoSuchMethodError: 
'org.pac4j.core.profile.InternalAttributeHandler 
org.pac4j.core.profile.ProfileHelper.getInternalAttributeHandler()'] with 
root cause>

java.lang.NoSuchMethodError: 
'org.pac4j.core.profile.InternalAttributeHandler 
org.pac4j.core.profile.ProfileHelper.getInternalAttributeHandler()'

Any idea where this issue could come from?

>From my understanding, pac4j is the component evaluating the identity's 
attributes coming from CAS server.

With CAS Management in debug log-level, I can see all attributes of the 
authenticated identity coming from CAS server in the cas-management.log.

Could it be a dependency issue? I build CAS Management with the following 
gradle properties : 
# Versions
casmgmt.version=6.2.2
cas.version=6.2.5
springBootVersion=2.2.8.RELEASE
appServer=-tomcat
sourceCompatibility=11
targetCompatibility=11
gradleMavenPluginVersion=5.1.1
