             Summary: JPA .schema-generation-action compliance issue
                 Key: WFLY-2744
                 URL: https://issues.jboss.org/browse/WFLY-2744
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: JPA / Hibernate
    Affects Versions: 8.0.0.CR1
         Environment: windows
            Reporter: Leos Literak
            Assignee: Scott Marlow


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.
