A a Jira administrator I'd like to have an easier way to get all the classes used in a workflow descriptor for post-functions, validators and conditions, without depending on the DB type.

Currently there's a suggested solution available for PostgreSQL DB types only:

A suitable solution to be used disregarding the DB type is desirable.
