Jasperserver error on xml working on iReport

[sbced]

I'm using Jasperserver 3.7.1 and iReport 4.0.0

On IReport I've 2 fields

    <field name="RBA" class="java.math.BigDecimal"/>
    <field name="MAV" class="java.math.BigDecimal"/>
 

and I'm trying to display a field with the sum

            <textField pattern="#,##0;-#,##0">
                <reportElement x="99" y="638" width="68" height="20"/>
                <box rightPadding="3">
                    <pen lineWidth="0.5"/>
                    <topPen lineWidth="0.0"/>
                    <leftPen lineWidth="0.0"/>
                    <bottomPen lineWidth="0.0"/>
                    <rightPen lineWidth="1.0"/>
                </box>
                <textElement textAlignment="Right" verticalAlignment="Middle">
                    <font size="7"/>
                </textElement>
                <textFieldExpression class="java.lang.Double"><![CDATA[$F{RBA}.doubleValue()+$F{MAV}.doubleValue()]]></textFieldExpression>
            </textField>
 

On iReport I can compile and preview: all ok.

But on Jaspersever called via browser

http://xxxxx:8080/jasperserver/flow.html?_flowId=viewReportFlow&reportUnit=/reports/Apex/SK_CLIENTE_FG&output=pdf

I've he error:

Error Trace:

Suggestions?

The simple solution is: don't use JasperServer 3.7.1 and iReport 4.0.0.

They are not compatible. JR is generally very good at being backwards compatible. But it's not "forwards compatible". Use iReport 3.7 with JasperServer 3.7, and things should all be good.
