             Summary: Adding simple-permission-mapper with some permission throws NPE
                 Key: WFLY-7082
                 URL: https://issues.jboss.org/browse/WFLY-7082
             Project: WildFly
          Issue Type: Bug
          Components: Security
            Reporter: Ondrej Lukas
            Assignee: Darran Lofthouse


Adding simple-permission-mapper with ChangeRoleMapperPermission or RunAsPrincipalPermission throws NPE. In case when LoginPermission is used then it works correctly.

{code}
/subsystem=elytron/simple-permission-mapper=SomeMapper:add(permission-mappings=[{roles=[All],permissions=[{class-name="org.wildfly.security.auth.permission.ChangeRoleMapperPermission"}]}])
{
    "outcome" => "failed",
    "failure-description" => {
        "WFLYCTL0080: Failed services" => {"org.wildfly.security.permission-mapper.SomeMapper" => "org.jboss.msc.service.StartException in service org.wildfly.security.permission-mapper.SomeMapper: Failed to start service
    Caused by: java.lang.NullPointerException"},
        "WFLYCTL0412: Required services that are not installed:" => ["org.wildfly.security.permission-mapper.SomeMapper"],
        "WFLYCTL0180: Services with missing/unavailable dependencies" => undefined
    },
    "rolled-back" => true
}
{code}

NPE occurs in server log:
