On a new project in 5.4.10 Magnolia can't start.

I excluded the magnolia-lang-ko and it works.

<dependency>
<groupId>info.magnolia</groupId>
<artifactId>magnolia-empty-webapp</artifactId>
<type>pom</type>
<exclusions>
<exclusion>
<groupId>info.magnolia.lang</groupId>
<artifactId>magnolia-lang-ko</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>info.magnolia</groupId>
<artifactId>magnolia-empty-webapp</artifactId>
<type>war</type>
<exclusions>
<exclusion>
<groupId>info.magnolia.lang</groupId>
<artifactId>magnolia-lang-ko</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>

because the module descriptor depends on scheduler 2.2.3 instead od 2.2.1, see the following dependency:tree
