Check for circular references added to SearchInventoryImpl to prevent recursive call
Resolved in Pega Version 8.4.2
An out of memory error was traced to SearchInventoryImpl infinitely recursing over a clipboard property, where the child property referenced a parent property and resulted in an endless loop. This has been resolved with the addition of a depth check to ensure that the search does not recurse infinitely.

Handling added for hotfix Rule-Application instances
Resolved in Pega Version 8.4.2
A null pointer error during DL file expansion performed as part of the second phase of a hotfix installation caused the hotfix install to fail. The null-pointer exception was thrown because the code, primarily used for export, performed a database lookup of a Rule-Application and assumed the response would be non-null without checking the result. During export the Rule-Application would normally exist because the system would have interacted with it already during the export by identifying it and writing it to the archive. During phased hotfix installation, rules are staged to the database in a different table during the first phase and reconstituted during the second phase. The scenario for this error was a missed corner case specific to the unusual combination of including Rule-Application instances in a platform hotfix. To resolve this and prevent further issues, handling has been added for this use case.
