> h4. Details
> Please see attached sample web application and run it via:
> {code} mvn clean compile jetty:run {code}
> At startup we can see huge stack trace that tells literally nothing.
> {code:java}
> 2015-07-01 16:38:50.076:WARN:oeja.ServletContainerInitializersStarter:main:
> org.jboss.weld.exceptions.DefinitionException: Exception List with 1
> exceptions:|Exception 0 :|java.lang.RuntimeException: Failed initializing
> mapping files

> {code}
> Whereas the exception should look like:
> {code:java}
> javax.servlet.ServletException: Caused by:
> javax.persistence.PersistenceException: [PersistenceUnit: netadminPU] Unable
> to resolve named mapping-file [META-INF/jpql/named-queries.xml]
> {code}
> _Because corruption is about pointing out to a not-existing mapping file
> named {{named-queries.xml}}_
> h4. Known workarounds
> # Of course we can fix the corrupted {{persistence.xml}} file, by removing
> line:
> {{<mapping-file>META-INF/jpql/named-queries.xml</mapping-file>}}
> # We can also remove dependency to "deltaspike-data" from {{pom.xml}} as it
> solves the issue
> Because then we got perfectly clear and correct message that tells us what
> is wrong with {{persistene.xml}}.
> For further details, please see file *README.md* inside attached application.
> BTW: Why does the DeltaSpike parse persistence.xml at application startup?
> Shouldn't this file be parsed with a lazy manner, at first usage of the
> EntityManagerFactory?
