[jboss-jira] [JBoss JIRA] (AS7-2275) Deployment error should result when ambiguous injection is specified

[Scott Marlow (JIRA)]

    [ https://issues.jboss.org/browse/AS7-2275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12782729#comment-12782729 ] 

Scott Marlow commented on AS7-2275:
-----------------------------------

[~jaikiran] [~stuartdouglas] it has been a few years since we discussed this change.  The JPA specification does not require us to fail the deployment when applications fail to specify which persistence unit should be used.  I think that it would be better to make this a warning, which I will create a pull request for doing (via WFLY-1032).  By "better", I mean it will be easier to migrate applications to WildFly.

Since the pull request will be against WFLY-1032, could everyone please comment there.

> If no name is specified PersistenceUnitSearch.resolvePersistenceUnitSupplier will return a PU at random, rather than throwing an exception if more than one PU is found.
