[jira] [Resolved] (DIRAPI-348) NPE when Api decodes bind response from OpenDJ server 6.0

["Emmanuel Lécharny (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DIRAPI-348?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Emmanuel Lécharny resolved DIRAPI-348.
--------------------------------------
    Fix Version/s: 2.1.1
                       (was: 3.0.0)
       Resolution: Fixed

We now check that the Control factory returns a Null value, and don't generate anymore a NPE, but instead create an {{OpaqueControl}} instance containing the {{byte[]}}, up to the user to deal with the unknown control: 

{code}
            ControlFactory<?> factory = container.getControlFactory();
           
            if ( factory == null )
            {
                // We don't know about this control, so it's an opaque control 
                ( ( OpaqueControl ) control ).setEncodedValue( value.getData() );
            }

{code}

> User can use our application to reset the password, even if they do not know their old ones.
> In the first step, the application resets the password and uses the temporary password for the bind request with the intention to change the password.
> During the decoding of the response, there is a control sent back, for which there is no factory defined, and a NullPointerException is thrown.
> This is the control in question:
> controlType: 2.16.840.1.113730.3.4.4, controlValue: an octet string: "0", criticality: false
>  
> Attached is the stacktrace, and implementation ideas for a new control
