Is this to say that in applications with multiple persistence units a validator factory is created for each PU? If so, I don't think that's neccessary as I'm not aware of any PU-specific configuration related to validation.

That's right. Maybe I am just not sure what this issue stands for.

Instead the same VF can be used for all the PUs of one application which will save memory.

Right

But with WFLY-1705 done, this should actually be the case, i.e. JPA consistently uses the one and only (in the context of one application) LazyValidatorFacotry (I think that's what Scott is saying).
{quote}
If this is the case, I am fine. Then I just need to find out why my test case ( see [HV-837|https://hibernate.atlassian.net/browse/HV-837]) is not working.

> Currently, a new bean validator factory instance is associated with each deployed persistence unit.  This jira calls for adding a new PU property that specifies that a 'per app bean validator factory' should be used for a persistence unit (via a persistence unit property).
> This can be controlled by a new persistence unit property (see existing ones [here|https://docs.jboss.org/author/display/AS71/JPA+Reference+Guide#JPAReferenceGuide-Persistenceunitproperties]).
> The new property can be something like "org.jboss.as.jpa.shareValidatorFactory" which defaults to false.  
> Look at org.jboss.as.jpa.processor.PersistenceUnitDeploymentProcessor.deployPersistenceUnit() to make this change.
