[jira] Resolved: (OPENJPA-1038) Enhancer
java.lang.StackOverflowError exception when circular dependencies are
encountered within embeddables
[ https://issues.apache.org/jira/browse/OPENJPA-1038?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tim McConnell resolved OPENJPA-1038.
------------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0
Issue is now resolved as the Enhancer (as of r765846) is able to detect indirect circular dependencies without getting stack overflow exceptions and it also outputs a more useful Exception message as below:

> 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.
