Exception getting olap4j conection in pentaho 5.2

I have two Pentaho plugins. One made in GWT work in 5.0-5.2 and return all dimensions I need. Now I need refactoring without gwt. I put conection code in my new REST service and code work well in pentaho 5.0 but fail in 5.2. I believe the problem is not in the code but i trying to understand why it fail if in the gwt service work well.

    MondrianProperties pr = MondrianProperties.instance();

    // Customize Mondrian to get connection
    pr.setProperty("mondrian.rolap.ignoreInvalidMembers", "true");
    pr.setProperty("mondrian.rolap.ignoreInvalidMembersDuringQuery", "true");
    pr.DataSourceResolverClass.setString("org.pentaho.platform.web.servlet.PentahoDataSourceResolver");

    Properties props = MondrianPropertyLoader.loadProperties();
    for(String property: props.stringPropertyNames()) {
        pr.setProperty(property, props.getProperty(property));
    }

    url = "jdbc:mondrian:Catalog=" + catalogDefinition + ";Datasource=" + dataSource; // + props;
    Class.forName("mondrian.olap4j.MondrianOlap4jDriver");

    // In Pentaho 5.2 RESTService fail
    // ---------------------------------
    OlapConnection connection = (OlapConnection) DriverManager.getConnection(url, "", "");
    // ---------------------------------

    final OlapWrapper wrapper = connection;
    OlapConnection tmpolapConnectionStx = (OlapConnection) wrapper.unwrap(OlapConnection.class);
    olapConnection = tmpolapConnectionStx;

    //Roles stuff
    setRoles(connection.getAvailableRoleNames());

    connection = null;
    Class.forName("mondrian.olap4j.MondrianOlap4jDriver");

    url += ";Role=" + getStringRoles();
    connection = (OlapConnection) DriverManager.getConnection(url, "", "");
    final OlapWrapper wrapper2 = connection;
    tmpolapConnectionStx = null;
    tmpolapConnectionStx = (OlapConnection) wrapper2.unwrap(OlapConnection.class);
    if (tmpolapConnectionStx == null) {
        throw new Exception("Connection is null");
    }
    olapConnection = tmpolapConnectionStx;
    this.initialized = true;

Previous code is the same for both, but in my new service in Pentaho 5.2 the line

OlapConnection connection = (OlapConnection) DriverManager.getConnection ...

fail and throw following exceptions with this urls

jdbc:mondrian:Catalog=mondrian:/SampleData;Datasource=SampleData;Provider:mondrian;EnableXmla:false

jdbc:mondrian:Catalog=mondrian:/SampleData;Datasource=SampleData

Both plugins are the same pentaho and has the same mondrian properties, so i don't understand why its happen.
