CAS 6.1.6 and taskExecutor not found

[Matthieu Marc]

Hello,

I am running CAS 6.1.6 (https://gitlab.ensam.eu/auth/cas-server.git branch 6.1) from gradle overlays with those dependencies :

dependencies {
    compile "org.apereo.cas:cas-server-webapp-tomcat:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-ldap:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-json-service-registry:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-memcached-ticket-registry:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-memcached-spy:${project.'cas.version'}"
    compile "org.apereo.cas:cas-server-support-audit-jdbc:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-jdbc-drivers:${casServerVersion}"
    compile "org.apereo.cas:cas-server-support-person-directory:${casServerVersion}"
    compile "org.apereo.cas:cas-server-core-events-configuration:${casServerVersion}"
}

I put my configuration in /etc/cas/config as expected, with all log4j level to debug.

I build the archive and run it : java -jar build/libs/cas.war

Just after the "READY" message, I got this error :

I don't know what to do to resolve this problem. I don't know if it is really a problem, but since I ran 6.1 version, when modifying configuration in applications.properties, the configuration is not reloaded automaticaly (it does so on my 5.2.9 version).
