[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=12782859#comment-12782859 ] 

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

We could let the application pick the default (via pu property) instead of the current approach (which isn't random, the same search order is done every time during deployment).

The randomness would come in because the JPA specification doesn't define exactly how containers should pick the correct persistence unit.  So, different application servers might pick a different pu.

> 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.
