>             Project: WildFly
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: JPA / Hibernate
>    Affects Versions: 8.0.0.CR1
>         Environment: windows

> I had following persistence.xml in my war application:
> <?xml version="1.0" encoding="UTF-8"?>
> <persistence version="2.1"
>     xmlns="http://xmlns.jcp.org/xml/ns/persistence"
>     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
>   <persistence-unit name="OAUTHDEMO" transaction-type="JTA">
>     <jta-data-source>java:jboss/datasources/test</jta-data-source>
>     <exclude-unlisted-classes>false</exclude-unlisted-classes>
>     <properties>
>         <property name="javax.persistence.schema-generation.database.action" value="create"/>
>     </properties>
>   </persistence-unit>
> </persistence>
> When I ran it second time, deployment failed because table already existed. I downloaded JPA specification to read how it is defined and there is such statement:
> javax.persistence.schema-generation-action
> The javax.persistence.schema-generation-action property specifies the
> action to be taken by the persistence provider. If the javax.persistence.
> schema-generation-target property is not specified, no action must be
> taken, regardless of the value of the javax.persistence.schema-generation-
> action property. The values for this property are "none", "create",
> "drop-and-create", "drop".
> Following sentence is interesting, because I do not have the schema-generation-target property defined:
> If the javax.persistence.
> schema-generation-target property is not specified, no action must be
> taken, regardless of the value of the javax.persistence.schema-generation-action property. 
> So unless I misunderstood this line, then JPA implementation is incorrect.
