I´m getting the following error if I have more than 1 realm:

class io.buji.pac4j.subject.Pac4jPrincipal cannot be cast to class java.lang.String (io.buji.pac4j.subject.Pac4jPrincipal is in unnamed module of loader

Issue is here:

Shiro.ini

securityManager.realms = $pac4jRealm, $jdbcRealm, $tcRealm

    

Here my pom.xml

<pac4jVersion>5.7.7</pac4jVersion>
<bujiVersion>8.1.0</bujiVersion>
<jeePac4jVersion>7.1.0</jeePac4jVersion>

    

How can this be solved?
Is this a bug in the Pa4j library – why is it not converted to String?

Let me know if you need more information.
