      Remove or correct the invalid permissions.

      Since there is no error detailing which permission is wrong, this entails trial and error to isolate the affected permissions.

      • Configure the security manager subsystem with an invalid permission in the mininum-set. Maximum-set must be present, but can contain anything except java.security.AllPermission. 
        <subsystem xmlns="urn:jboss:domain:security-manager:1.0">
     <deployment-permissions>
         <minimum-set>

      If the security manager contains an invalid class or other data in the minimum-set it throws a NullPointerException instead of a useful error message.

      ERROR [management-operation] WFLYCTL0013 : Operation ("add") failed - address ([("subsystem" => "security-manager")]): java.lang.NullPointerException 
 at java.security.Permissions.getPermissionCollection(Permissions.java:240)

...

      The same thing happens with other missing data.

      • Works: 
        <permission class="java.io.FilePermission" name="/foo" actions="read"/>
      • Fail with NullPointerException: 
        <permission class="invalid.class.name" name="/foo" actions="read"/>
        <permission class="java.io.FilePermission" name="/foo"/>
        <permission class="java.io.FilePermission" actions="read"/>

      The NullPointerException does not occur if maximum-set is absent, or contains java.security.AllPermission
