Build Identifier: 

NullPointerException error when I convert Association Class to Association on Class diagram.

1. Create Tigerstripe project with 3 entities and association class. 
2. Extend Association Class to the Entity.
3. Create class diagram and add Association Class to the diagram.
4. Select Association Class line and select 'convert to Association'

As a result, the error is erased:
An internal error occurred during: "Model updating...".
java.lang.NullPointerException

See error log:
java.lang.NullPointerException
