[jira] Commented: (OPENJPA-620) OpenJPA configuration setting that guarantees that once the EMF is created, it will be fully-configured

["Patrick Linskey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-620?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12602298#action_12602298 ] 

Patrick Linskey commented on OPENJPA-620:
-----------------------------------------

An important first step is to have a single method that can be invoked against a Configuration (or EMF or BrokerFactory) whose role it is to perform this work.

AbstractBrokerFactory.makeReadOnly() is in the wrong place, and is invoked by existing code that might not expect it to have the same semantics. Maybe Configuration.setReadOnly() with some new state (plus documentation)?

> Lot of the processing - like the loading of configured persistent types, processing the metadata for the registered classes happens at the time of creating an EM or even later when the metadata resolution is needed. Having a configuration where the obtaining of the EMF does all this processing would be useful for early detection of errors, and for managed environments where this could be done as a part of an application deploy step rather than happening at runtime.
