Description

Using OpenDS 2.2 (latest version at this time), the Schema Editor cannot successfully load the online schema from the connection because of a badly formatted attribute type description returned by OpenDS.
This is clearly a bug on OpenDS's side and a JIRA has been opened to address this issue OPENDS-4616 http://java.net/jira/browse/OPENDS-4616.

Instead of failing badly, Studio should discard this particular attribute type and move to the next one.
This would leave the project in a better state, rather than having strictly nothing after the import.

Here's the full console report:
