stackoverflow while integrating eclipselink with jboss eap 6 - jpa

Question

I am trying to deploy an application configured with eclipse link as jpa provider on jbosss eap 6.3
but it seems there is an issue between EclipseLink and jboss because i get a stackoverflow error while deploying
Failed to define class org.eclipse.persistence.internal.weaving.WeaverLogger in Module "deployment.test-service.war:main" from Service Module Loader: java.lang.StackOverflowError

Do i need to add some configuration to jboss(standalone.xml)?
There is my persistence.xml
<?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="unit" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:postgresql://*****" />
<property name="javax.persistence.jdbc.user" value="*****" />
<property name="javax.persistence.jdbc.password" value="****" />
<!-- EclipseLink should create the database schema automatically -->
<property name="eclipselink.ddl-generation" value="create-tables" />
<property name="eclipselink.ddl-generation.output-mode" value="database" />
<property name="eclipselink.logging.level" value="SEVERE"/>
</properties>
</persistence-unit>
</persistence>
My pom.xml(this project will be a dependency of another)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Any advices will be appreciated
Thank you very much

Thanks to Chris answer , i managed to run jboss eap 6 and EclipseLink by integrating eclipse link module inside jboss eap
I needed to create a new folder : JBOSS_ HOME\modules\org\eclipse\persistence\main and copy eclipselink.jar inside. Then i needed to create the module.xml associated
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.eclipse.persistence">
<resources>
<resource-root path="eclipselink.jar" />
</resources>
<dependencies>
<module name="javax.api" />
<module name="javax.persistence.api" />
<module name="javax.transaction.api" />
<module name="javax.validation.api" />
<module name="javax.xml.bind.api" />
<module name="org.antlr" />
<module name="org.apache.commons.collections" />
<module name="org.dom4j" />
<module name="org.javassist" />
<module name="org.jboss.logging" />
</dependencies>
</module>
Complete tutorial : https://docs.jboss.org/author/display/WFLY8/JPA+Reference+Guide#JPAReferenceGuide-UsingEclipseLink and http://www.eclipse.org/eclipselink/documentation/2.5/solutions/jboss002.htm
Moreover despites my server ran smoothly after that but i got a new error after trying persisting any data "object is not a known entity type"
The problem was because in the persistence.xml i had the line <exclude-unlisted-classes>false</exclude-unlisted-classes>
It seems there is a classloading issue between eclipselink and jboss eap
I needed to declare explicitely entities by <class> attributes
