I got above exception because I've table with subDataset containing <field> tag along with <fieldDescription> tag in it.

<field name="firstname" class="java.lang.String">
 <fieldDescription><![CDATA[]]></fieldDescription>
</field>

Solution
Remove <fieldDescription> tag from <field> tag.

<field name="firstname" class="java.lang.String"/>
