Hotfix hashmap cleanup improved
Resolved in Pega Version 8.2.4
A DL installation failed with an out-of-memory error. It was observed that many CacheEntry(VersionedJdbcJarRwader.java) hashmaps were being created to store the details for each hotfix but that were then never cleared. This has been resolved by adding the finally block in CodeImportProcessImpl.java class to call the shutdown method for proper cleanup. In addition, the default command line utility (prpcUtils) has been updated to use JVM settings of Xmx 4GB and capture a heap dump if an out-of-memory error is encountered. The auto-generated prconfig.xml has also been updated to leverage its minimal startup setting which will avoid loading the conclusion cache into memory.

Added differentiated handling for special symbols based on location in the label string
Resolved in Pega Version 8.2.4
While importing an Excel file into a decision table that used custom functions like@string:notequal or equal, label names like 'AlphaPrefix !=AAA' resulted in the error "invalid expression or reference: line 1:28 extraneous input '"True"' expecting {<EOF>, '-', '+', '=', '*', '/'," " . Investigation found that the problem was with the label of the column not handling the the special characters like (‘!=’, ‘<’ , ‘<=’, ‘>’, ‘>=’ ) present in the middle of the label string: the label and default operator were being updated irrespective of the location of the symbols within the string. To resolve this, DecisionTableWorkBookConverter.java has been modified to set the operator only if the special strings (‘!=’, ‘<’ , ‘<=’, ‘>’, ‘>=’ ) are present at the end of the label.

Step staus fail logic updated to handle agent activity exception
Resolved in Pega Version 8.2.4
Attempting to execute an advanced agent containing logic that set a step status to fail resulted in the error "Agent activity disabled due to execution errors; ErrorMsg: unable to execute agent: Cannot obtain a lock on instance as Requestor already has the lock ". This was traced to a backwards compatibility issue with previous work done to handle cases where agent activity requires authentication and agent has "bypass auth" flag set to false. Agent activity is not allowed to execute by the engine, and to show this scenario as exception case instead of showing it as running in admin studio, changes were made to rely on step status as the engine internally sets step status to false in this case. However, this inadvertently affected use cases where agent activity sets the status as fail in its logic. To resolve this, the system has been updated to handle the exception case and not consider StepStatus.

Null archive check added to set import process status
Resolved in Pega Version 8.2.4
After running a 'prpcServiceUtils.sh import' which failed due to a low-level null pointer error, the job "IMPORTREQUEST-2" then incorrectly showed the status as 'IN PROGRESS' instead of 'FAILED'. In this case, the null pointer exception occurred because two imports were unintentionally happening at the same time: the process copied up the same set of archives to the service export directory, but the first import processed an archive and deleted it so that the second process failed to find it. When it exited with the null pointer exception, the status was not set to 'failed'. To resolve this, a null archive check has been added which will set the status to 'failed' if the archive is unsupported, corrupt, or not there at all.
