hsqldb and GenerationType.IDENTITY generates incorrect sql when the table has only one column
---------------------------------------------------------------------------------------------

                 Key: OPENJPA-1947
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1947
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 2.0.0
            Reporter: Vermeulen
            Priority: Minor


I use hsqldb for simple tests and let OpenJPA generate the tables with the line
<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"
/>
in persistence.xml.

When I make an entity with an id column like:

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Long id;

And possibly some relations that do not result in extra columns in the table, OpenJPA generates
wrong SQL when persisting a new entity:
