Resolved 400 error on second browser session
Resolved in Pega Version 8.5.1
When accessing application URLs in two tabs of a browser window, logging into the second session was throwing a 400 invalid request. This has been resolved by adding specified activities to an allow list which will bypass URLObfuscation in un-authenticated mode. Non-listed activities will be processed using URLObfuscation if it is enabled.

Timezone.getDefault function replaced for performance improvement
Resolved in Pega Version 8.5.1
Blocking threads were seen around the GregorianCalendarFactory.clearObject(Object) function, leading to an adverse impact on the performance. TimeZone.getDefault() is a synchronized method call, and under high load this method caused contention when more date-related APIs were invoked. To resolve this, Timezone.getDefault() has been removed and the function has been assigned to a static variable used in the clearObject() API.

Class Loader cache values wrapped with WeakReference for improved cleanup
Resolved in Pega Version 8.5.1
Out Of Memory exceptions due to Metaspace were observed on Web tier instances running with a max Metaspace size of 2GB. Investigation showed that in PRClassLoaderDB, mLoaderCache values were wrapped with a SoftReference. To resolve this, the Class Loader cache values will be wrapped with a WeakReference, allowing the cache to free memory when it is no longer needed. JVM options has also been added to switch types of References being used if there is a preference.

Delay in writing database template records resolved
Resolved in Pega Version 8.5.1
After upgrade. a real-time event based campaign with an offer flow that used a database template showed an excessive delay in updating the database template. A queue entry related to "WriteOutboundAgent" was also showing as failed, and analysis of the logs showed that the transaction type was not being set. This was traced an exception during a regular close operation of the result set iterator: the API used to close the transaction contained code specific to PostgreSQL while the site was using Oracle. This has now been resolved.

Encrypted SOAP response token generation updated
Resolved in Pega Version 8.5.1
After configuring a SOAP service that used signature and encryption on the response, the response being created was incorrect and could not be decrypted by the receiver. Investigation showed that the API used to generate the SOAP headers was not setting the wsse11:TokenType element, causing receivers which enforce BSP compliance to fail. This has been resolved by modifying the custom webservices-rt-pega2 jar to set the token type in the case of a response encryption policy.

EmailListener restart correctly reflects Inbox folder change
Resolved in Pega Version 8.5.1
The Email Listener did not pick up a change in the INBOX folder name when the listener was restarted, but did when the server itself was restarted. This was due to the folder name being cached but not being included in the cache key: a cache change only occurs when the key of the cache changes. This meant that even after changing the folder name, the object was treated as 'not changed' and returned the older connection with older folderName. This has been resolved by adding the foldername to the cache key.

Removing PageList removes all cached pages
Resolved in Pega Version 8.5.1
A previous change was made such that when removing a pageList property, its size is removed from the size-specific cache as well. A further enhancement has been made so that when a PageList is removed, the system will clear the pageCache of all cached pages in the PageList.
