OAuth token refreshed when revoked on source
Resolved in Pega Version 8.7
When an OAuth token was used to authorize the APIs in the system, revoking the token at the source, i.e. from the Service side, did not automatically refresh the token and a logoff/logon was required before a fresh token was generated. This has been resolved by adding an update to explicitly purge revoked tokens.

Guided Tour working from Actions menu
Resolved in Pega Version 8.7
After updating from Pega 8.4 to Pega 8.5, "Manage a Guided Tour" was no longer working under a local action when called from the Actions menu on a work object. An unspecified error message appeared in the tracer. Investigation showed there was a null pointer error caused by the menu being invoked on an invalid page, and this was traced to updated authentication requirements: registration at the portal is not reliable as it is thread-scoped and run only once. The thread name is not guaranteed to stay the same so subsequent invocations of the tour activities failed. This has been resolved by modifying the call registration function to handle the security issues related to the generation of the menu path.

LookUpList correctly executes during SSO login with model operator
Resolved in Pega Version 8.7
After configuring SSO to create operators on fly using a model operator, a new user logging in for the very first time had their operator ID created using the model operator, but after upgrade new users logging in to the system received the error "Only authenticated client may start this activity: RULE-OBJ-ACTIVITY @BASECLASS LOOKUPLIST". This was due to the methods used for additional security on the activity @baseclass LookUpList which allows it to only be run by authenticated users, and has been resolved.

Web Tier busy threads released on timeout
Resolved in Pega Version 8.7
Tomcat Web Tier Busy Threads were not being correctly released, causing stability and performance problems that included health check pings not receiving a thread to service the request so the node was marked as bad, users were quiesced, and the node replaced. Investigation showed the 'put' on the blocking queue did not time out when the queue was full and waited indefinitely, keeping the thread blocked. To resolve this, the system will use 'offer' on the blocking queue instead of 'put' to force thread release on timeout. In addition, debug logs have been added to understand when the offer (or Put) does not succeed and the state of the queue that is causing this issue; the debug logs for class com.pega.pegarules.session.internal.serverpush.RoboticAutomationImpl should be enabled only if the thread busy issue is observed and for limited time window while actively debugging.

Check added to ensure read locks are released
Resolved in Pega Version 8.7
Read locks were not being properly released if a thread was holding a read lock and the system encountered an issue such as an out of memory condition. To resolve this, an update has been made to DeclarativePageDefinitionCacheImpl which will check whether a thread holds any read lock before trying to acquire a write lock, and if so release all the read locks held by that thread.
