[ https://issues.jboss.org/browse/WFLY-7219?page=com.atlassian.jira.plugin.... ] Ilia Vassilev commented on WFLY-7219: ------------------------------------- [~honza889] One way of knowing if "target-name" or/and "action" are required in the subsystem is to get the number of arguments from the permission class by implementing similar logic like PermissionUtil.createPermission or expose this functionality from Elytron. When we catch the exception in Elytron Subsystem we can throw a specific message if: 1. twoArg: "target-name" and "action" are both required 2. oneArg: "target-name" is required, "action" can be null. 3. noArgs: "target-name" and "action" are optional and can be null We already check if class-name is null. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
