Steps to Reproduce

Perform PRPC split-schema upgrade from 6.1 SP2 to 7.1.8 and try to bring up the PRPC instance

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules.

The customer seems to have defined a Rule-Access-When on the class Data-Admin-System-Settings. According to the current implementation, search is initialized before VTable is initialized. While initializing search, a DASS is set and while setting this DASS, a save operation is performed on the DASS which tries to perform a security check and the Rule-Access-When is attempted to be retrieved from
VTable cache which leads to NPE as VTable is not initialized causing the issue.

Resolution

This issue is resolved by hotfix item HFix-23062.
