             Summary: Module org.javassist not excluded when persistence.xml contains property <property name="jboss.as.jpa.providerModule" value="application" />
                 Key: WFLY-5743
                 URL: https://issues.jboss.org/browse/WFLY-5743
             Project: WildFly
          Issue Type: Bug
          Components: Class Loading
    Affects Versions: 9.0.2.Final
         Environment: OS: Windows 7
JVM: jdk1.7.0_79,
WF: wildfly-9.0.2.Final
DB: h2

Excluding the module 'org.javassit' in the jboss-deployment-structure.xml does not work correctly for all modules in EAR when shipping custom version of Hibernate and Javassist and setting property 
<property name="jboss.as.jpa.providerModule" value="application" />
in the persistence.xml.

In case of the following EAR structure:
{noformat}
EAR
 |`-- lib
 |     |`-- javassist-3.20.0-GA.jar
 |      `-- <hibernate 4.2.19 jars>
 |`-- META-INF
 |     |`-- jboss-deployment-structure.xml
 |      `-- application.xml
 |`-- EJB-JAR
 |      `-- META-INF
 |            `-- persistence.xml
  `-- WAR
{noformat}

and the content of the jboss-deployment-structure.xml
{code:title=jboss-deployment-structure.xml|xml}
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
	<ear-subdeployments-isolated>false</ear-subdeployments-isolated>
	<deployment>
		<exclusions>
			<module name="org.hibernate" />
			<module name="org.javassist" />
		</exclusions>
	</deployment>
</jboss-deployment-structure>
{code}
and persistence.xml
{code:title=persistence.xml|xml}
<?xml version="1.0" encoding="UTF-8"?>
<persistence 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"
	version="2.1">
	<persistence-unit name="cce-example" transaction-type="JTA">
		<provider>org.hibernate.ejb.HibernatePersistence</provider>
		<jta-data-source>jdbc/CCE_DS</jta-data-source>
		<properties>
			<property name="jboss.as.jpa.providerModule" value="application" />
		</properties>
	</persistence-unit>
</persistence>
{code}

The module EJB-JAR loads javassist classes not from the bundled {{EAR/lib/javassist-3.20.0-GA.jar}} but from {{<WF>/modules/system/layers/base/org/javassist/main/javassist-3.18.1-GA.jar}}
