Steps to Reproduce

  1. Create one activity using com.pega.apache.poi libraries in Pega 7.1.9.
  2. Upgrade environment to 7.2.2.
  3. Revalidate and save the activitiy.


Root Cause



An issue in the custom application code or rules

Resolution



Apache POI jar(s) have been upgraded to 3.15 version in Pega 7.2.2 and while doing the upgrade the package name(s) were not renamed to com.pega.apache.*.
Instead it can directly be used, that is, org.apache.poi.

All the Out-of-the-box (OOTB) rule(s) have been updated for the same.

Note: All the activities that user writes explicitly using the jars has to be changed to refer org.apache.poi.
