Deadlock in static Initialization of IntList resolved
Resolved in Pega Version 8.4
JVM Deadlock was seen related to the static Initialization of a subclass field in class com.pega.decision.strategy.ssa.runtime.collections.api.IntList . Thread dumps showed threads in RUNNABLE State that were parked to wait for class initialization, and this was traced to a missed sonar alert which failed in multi-threading. To resolve this, the system handling has been updated to prevent potential deadlock.

TTL value correctly passed for Adaptive Event store
Resolved in Pega Version 8.4
The ADM table was growing due to the Time to Live (TTL) for entries in the Adaptive Event Store not being propagated to clean them out. This was traced to the TTL field on the data flow not being checked, causing the TTL value to be supplied as zero so there was no expiration. This has been corrected.
