Type STRIKETHRU cannot be resolved or is not a field

[BO-fr]

Hi,
I've integrate "jasperreports-pdf-lib7" in my workspace, then have this issue :

STRIKETHRU cannot be resolved or is not a field JRPdfExporter.java /jasperreports-pdf-lib7/src/main/java/com/jaspersoft/jasperreports/export/pdf line 1728

com.itextpdf.io.font.FontConstants in : com.itextpdf.io (version 7.1.2) doesn't contains : FontConstants.STRIKETHRU.

Could you help me ?

Thks
