OSWorkflow implements several built-in components (functions, conditions, validators) integrating with e.g.:

• JNDI
• EJB
• Beanshell

While most of them is of arguable value, JIRA used to be able to successfully look up and instantiate them. While fixing JRA-20528 a bug was introduced in that JIRA no longer resolves those built-in components. The affected code is in DefaultOSWorkflowConfigurator. As a result, custom workflows using those facilities will face errors that will break their workflows. Note that those components are not used withing default JIRA workflows.
