Since upgrading Data Studio to the current version, a Data Solutions job that uses Dynamic Privacy Rules (DPR) for sanitizing data, now goes into an infinite loop, after processing a number of records.  The number of records, which varies from execution to execution.  The same job processed fine on v20.15.01.

As Data Studio version 23.01.01 and later no longer supports Java version earlier than v11, Java classes must be recompiled after upgrading Data Studio to ensure that existing custom functions work as expected after upgrading Data Studio from a version prior to 23.01.01. This requirement is documented under: Maintain Data Studio - Documentation for BMC AMI DevX Data Studio 23.01 - BMC Documentation.

After recompiling the java function, re-add the Custom Function to the Data Privacy Project.

Note: The capability to compile Java functions in Data Studio version 23.01.01 and later requires the integration of Java SDK to replace the java version that is delivered with the product.   

For instructions on how to implement this integration, refer to Knowledge Article:  BMC AMI DevX Data Studio 23.1.1 How to integrate Java SDK to a Workbench for Eclipse installation, which is required for compiling Java functions in the current version of Data Studio?.

Note:  Data Studio version 23.01.01 has a known defect that prevents the adding of a Custom Function to a Data Privacy Project. This issue is resolved in version 23.05.03.
