Workflow throwing exception while executing sub steps.

[toimrank]

Hi All,

We are migrating from AEM 6.1 to 6.4 and getting below exception while executing a workflow.

Its internal OOTB exception, which we are not able to debug.

Exception -->

UserManagerFactory#createUserManager is deprecated. UserManagerFactory ("The Adobe AEM Quickstart and Web Application.")
Looks like you are using it in UserNotification class.
