[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12788174#comment-12788174 ] 

Scott Marlow commented on WFLY-829:
-----------------------------------

Martin, which application server version are you deploying on?  WFLY-1032 is fixed for 8.0.0.Alpha2 (http://www.wildfly.org/download) to show more information as you say (if DEBUG logging is enabled for org.jboss.as.jpa).

The added DEBUG logging statement is in JPAAnnotationProcessor:
{code}
ROOT_LOGGER.debugf("persistence unit search for unitName=%s referenced from class=%s (annotation=%s)", searchName, classDescription.getClassName(), annotation.toString());
{code}

> When deploying an ear file that contains an Entity bean with an inappropriate @PersistenceContext annotation, the following stacktrace is generated, and the deployment fails:

> The IllegalArgumentException gives no data for the annotation, the class, or any relevant data to the cause.  I built JBoss debug from source to discover that the culprit in my case was a misplaced PersistenceContext annotation in an entity bean.  The offending annotation had actually existed in a version of our code running in JBoss 4 without error.
