Page Headers Truncation After Upgrade to Jasper Server 7.1.1

Hi All,

We recently upgraded to Jasper Server 7.1.1. Reports Headers are getting Truncated if the Text in the Field is lengthy. Prior to upgrade there were no Issue we Used only 3 below properties and got report with out any truncation.

    <property name="net.sf.jasperreports.print.keep.full.text" value="True"/>
    <property name="net.sf.jasperreports.export.xls.wrap.text" value="false"/>
    <property name="net.sf.jasperreports.export.xls.font.size.fix.enabled" value="false"/>

Truncation is happening only in Page Header (Column Names) but this is not happening in Detail Band (Data Repeating).We even didn't used Report element properties (Eg: Strech with Overflow checked)

Do we have any known issues in Jasper Server 7.1.1
