We have recently upgraded Jaspersoft to 7.1.0_6.1.0.28 in one of our non-production environments. We have observed that when the report is exported to excel, the column header is truncated (please refer to the attachment). Interestingly, this does not happen for the same report JRXML when run in another non-prod environment with the same Jasper version.
Please note that we have already used following settings in the reports -
<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"/>
Release : 15.4.1
