---------------------------------
Assignee: Fay Wang
> Enhancer java.lang.StackOverflowError exception when circular dependencies
> are encountered within embeddables
> -------------------------------------------------------------------------------------------------------------
>
> Key: OPENJPA-1038
> URL: https://issues.apache.org/jira/browse/OPENJPA-1038
> Project: OpenJPA
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: Tim McConnell
> Assignee: Fay Wang
>
> Circular dependencies among embeddable are not allowed. When they are
> encountered by the Enhancer it gets in an infinite loop causing a stack
> overflow exception as shown below. It seems there should be a more graceful
> detection of this scenario and a more useful explanation and/or description
> of the error. The failure is the same for both annotated and XML versions of
> the entities/embeddables.
