Cfspreadsheet.cfc Error after upgrade

I updated from to lucee 6 successfully.
Almost everything works except Excel sheet processing which was done via the cfspreadsheet.cfc 3.0.3 extension by Andrew Kretzer (akretzer).
After updating to lucee 6 I receive the following error:

Lucee Error (expression)
Message invalid component definition, can’t find component [org.cfpoi.spreadsheet.Spreadsheet]

I solved it by switching from LeftBower’s cfspreadsheet to CFsimplicity spreadsheet GitHub - cfsimplicity/spreadsheet-cfml: Standalone library for working with spreadsheets in CFML
A slight refactoring was necessary.
