Using Drools version 7.33.0.Final as well as 7.33.0.Final-redhat-00002.

When trying to upload an Excel Spreadsheet of type .xlsx I am getting a lot of error trying to upload the file. I am able to import the Excel file via the import Asset button, but not by using the "Add Asset" button and adding a new Spreadsheet asset and then uploading the Excel file.

So I am using OpenJDK 11.0.7 and I think that is the reason for the errors.

There are a lot of issues with the libraries from org.apache.poi version 3.17 (e.g. poi-3.17.jar, poi-ooxml-3.17.jar and poi-ooxml-schemas-3.17.jar) which are all part of the drools or decision-central war file. Using OpenJDK you have to use at least version 4.1.1 and update a few other dependancies like commons-compress-1.19.jar and xmlbeans-3.1.0.jar to get it to work.

I do not have a specific excel spreadsheet, but any spreadsheet of type .xlsx will cause the error when trying to upload it.
