Everytime I run grails test-app -unit I got following the stacktrace I
attached, but app can be successfully deployed on google app

My peristence.xml is this :

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd";
version="1.0">

    <persistence-unit name="transactions-optional">
 
<provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</
provider>
        <properties>
            <property name="datanucleus.NontransactionalRead"

            <property name="datanucleus.NontransactionalWrite"
value="true"/>
            <property name="datanucleus.ConnectionURL"
value="appengine"/>
        </properties>
    </persistence-unit>

</persistence>


Any idea about this?
