[#4846] - xlsx exporter sending corrupt hyperlinks' data

Dear All;
We are using Jasperserver to run monthly reports of a considerable size.
The reports contain a hyperlink in of the columns and we need to export them in xlsx format because of the size of the data.
- When we the report for a shorter time, resulting into a smaller report of less than 4000 rows, and export to xlsx we encounter no problem. The report is properly downloaded and can be opened with MS Excel.

- But we run the report with more data that results in a report of more 4000 rows; after downloading, on trying to open the exported xlsx file MS Excel states that the file contains ivalid data and further asks if i would like it corrected.
If i choose i yes, MS Excel reports during the correction of the data, some parts were removed a log containg the following is displayed;

<?xml version="1.0" encoding="UTF-8" standalone="true"?>
-<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<logFileName>error245400_01.xml</logFileName>
<summary>Errors were detected in file 'C:\Users\myusername\AppData\Local\Temp\e1_broker_report-9.xlsx'</summary>
-<additionalInfo>
<info>Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.</info>
</additionalInfo>
-<removedFeatures summary="Following is a list of removed features:">
<removedFeature>Removed Feature: Hyperlinks from /xl/worksheets/sheet2.xml part</removedFeature>
</removedFeatures>
</recoveryLog>

I have read around and many experiencing a similar problem claim the issue is in the JRXlsxExporter. But from my own observations, it seems like the size of the report has something to do with the problem. I think so because for slightly smaller reports, we do not observe the problem.
