Steps to Reproduce

Root Cause

A defect or configuration issue in the operating environment.

Multiple versions of the Guava Library (15.0, 18.0, and 19.0) were stored in the Pega database. However, only Guava Library 19.0 was shipped with Pega.


  1. Run the following query in the database:

    update <rules schema>.pr_engineclasses set pzcodeset='your_customerCodeset' where pzjar like '%guava%' and pzcodeset='customer';

    This prevents the older Guava library versions from being added to the classpath during startup.
  2. Restart the application server.
