Проблем с JPA Dialect nosuchmethod изключение

Опитвам се да създам тестова среда за моята компания. Те са избрали да използват JPA, за да се свържат с базата данни на microsoft sql сървъра. Проблемът възниква, когато пресъздадох базата данни и използвайки техния изходен код, не мога да се свържа с нея. Това е грешката junit, която получавам (все още за диалекта, не за junit)

След това прочетох малко и открих, че това обикновено се причинява от конфликт на библиотека:

hibernate-commons-annotations.jar 4.0.5 
hibernate-entitymanager.jar
hibernate-c3p0.jar 4.3.8
hibernate-core.jar 4.3.8
hibernate-entitymanager.jar 4.3.8 final
hibernate-validator.jar 5.1.3 final
hibernate-jpa-2.1-api.jar 1.0.0 final
c3p0.jar 0.9.2.1 

Информация за JPA:

<persistence-unit name="TestPU" transaction-type="RESOURCE_LOCAL">      
<properties>
<property name="hibernate.connection.url" value="jdbc:log4jdbc:sqlserver://127.0.0.1:1433;database=JPADB;" />
<property name="hibernate.connection.driver_class" value="net.sf.log4jdbc.DriverSpy" />
<property name="hibernate.dialect" value="com.companyname.kernel.persistence.jpa.UnicodeSQLServerDialect" />
<property name="hibernate.connection.autocommit" value="true" />
<property name="hibernate.show_sql" value="false" />
<property name="hibernate.hbm2ddl.auto" value="update" />


<!-- use c3p0 connection pool -->
<property name="hibernate.c3p0.min_size" value="3" />

<property name="hibernate.c3p0.timeout" value="1800" />
<property name="hibernate.c3p0.max_statements" value="0" />  
</properties>

Код от диалекта:

registerColumnType( Types.VARBINARY, "image" );
    registerColumnType( Types.VARBINARY, 8000, "varbinary($l)" );
    registerColumnType( Types.LONGVARBINARY, "image" );
    registerColumnType( Types.LONGVARCHAR, "text" );
    registerColumnType( Types.BOOLEAN, "bit" );

Ново откритие: Използвах eclipse от моя лаптоп, за да се свържа със сървъра на базата данни и той работи, но когато Дженкинс се опитва да го направи, дава грешка по-горе.

Не можах да намеря нищо нередно с тях, но се надявам някой от вас да отдели време да ми помогне. Всякакви насоки са добре дошли.
