      1. Add the following persistence.xml to helloworld-mbean-webapp in WildFly QuickStarts "helloworld-mbean"

      helloworld-mbean-webapp/src/main/resources/META-INF/persistence.xml
      <?xml version="1.0" encoding="UTF-8"?>
      <persistence version="2.1"
          xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="
              http://xmlns.jcp.org/xml/ns/persistence
              http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
          <persistence-unit name="example">
              <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source>
              <properties>
                  <!-- Properties for Hibernate -->
                  <!-- <property name="hibernate.hbm2ddl.auto" value="create-drop" /> -->
                  <property name="hibernate.show_sql" value="false" />
              </properties>
          </persistence-unit>
      </persistence>
      

      2. Build and deploy helloworld-mbean-webapp.war to WildFly 18.0.0.Final

      3. Start WildFly 18.0.0.Final

      You will see that the deployment fails due to NullPointerException.

      Description

      When a web application contains both MBean (jboss-service.xml) and persistence-unit (persistence.xml), the WAR deployment fails due to the following NullPointerException:

          ]
      }
      

      This NPE happens because WebNonTxEmCloserAction#dependencies() returns null. It should return Collections.emptySet() instead of null.
