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.

ContextMap cache handling updated to address reverse map corruption
Resolved in Pega Version 8.5.1
An issue was seen with intermittent login failures. A network trace revealed indefinite 303 redirects happening during the attempted connection. If the access group was resaved under a new name, the login worked. This was traced to a thread issue in Java’s implementation of PBEKeySpec that caused the reverse ContextMap cache to become corrupted. To resolve this, the system has been updated to compare the access group from the reverse map and the access group passed for encryption (which will always be correct) and correct the map if necessary.

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.

Changed rounding mode notification from error to informational message
Resolved in Pega Version 8.5.1
Pega server recycle was indicating there were errors even though Pega RULES had initiated successfully. This was traced to the default rounding mode message being categorized as system.err which caused it to appear as an error instead of as an informational message. This has been resolved by changing the logging to be system.out .
