p:dataExporter xlsx problem

[Desarrollointelidata]

The Problem is generated when exporting a datatable as xlsx.
I have tried different versions of poi-ooxml 3.14, 3.8, 3.11 and I have the same problem.

java.lang.AbstractMethodError: Method org/apache/poi/xssf/usermodel/XSSFSheet.getMergedRegions()Ljava/util/List; is abstract
at org.apache.poi.xssf.usermodel.XSSFSheet.getMergedRegions(XSSFSheet.java)

I think it is not a Layout or Theme issue. Could you please try it without Ultima? Please use PrimeFaces core forum; viewforum.php?f=3

Also, we use the following dependencies in PrimeFaces showcase;
