Rules can no longer access Pega internal Java packages
Valid from Pega Version 8.4
You can no longer create rules that access Java packages that reference internal APIs (syntax com.pega.platform.*.internal*
). This change does not affect rules that access Pega public API packages.
If you encounter issues when running existing rules that reference internal Pega APIs, contact Pega Support.
Upgrade impact
After an upgrade to 8.4 and later, clients can no longer save new or modified rules that access Pega internal APIs; existing rules that reference internal APIs can still be run but cannot be modified.
What steps are required to update the application to be compatible with this change?
Following a software upgrade to 8.4 or later, clients can refactor existing rules into guardrail compliant rules. To find rules to refactor, run the validation tool from designer studio (Application > Tools > Validation) to identify what rules fail validation; failed rules that include the message "Test compilation failed : Illegal internal class reference : com.pega.internal.XYZ" can updated to reference appropriate APIs.
