Description

Spreadsheet has some dependencies that are not provided as OSGi bundles. One example is Apache POI, for which there is a bug open https://bz.apache.org/bugzilla/show_bug.cgi?id=57857. Also according to apache POI documentation, only versions > 3.16 can be used with OSGi

Therefore, although spreadsheet itself can be installed, it can not be used to create applications. Trying to deploy a portlet that depends on spreadsheet generates the following error:

Unresolved requirement: Import-Package: org.apache.poi

Since Spreadsheet is provided is an OSGi bundle, and therefore appears to work, I think it would make sense to either document that it is not supported or provide some kind of example of how it can be used.

Research direction

No repository files or tests are named. Start by reviewing how Apache POI is declared and how Spreadsheet is packaged as an OSGi bundle, then compare this with Apache POI's OSGi requirements. Done means the limitation is clearly documented or a working OSGi usage example is provided, addressing the reported unresolved Import-Package error.
