Hibernate Validator 4.3.0 was responsible for memory saving not the property.

I already done it. But the problem is that if I make side by side comparison
between memory dumps from JBoss 4 and JBoss 7 I don't see a big difference. :-(
Only the size of SessionFactoryImpl differs.

No problem. Here it is:
<persistence-unit name="MyEntityManager">
<jta-data-source>java:/MyDS</jta-data-source>

<property name="hibernate.default_batch_fetch_size" value="16"/>
<property name="hibernate.order_updates" value="true"/>
<property name="hibernate.order_inserts" value="true"/>
<property name="hibernate.jdbc.fetch_size" value="50"/>
<property name="hibernate.jdbc.batch_size" value="15"/>
<property name="hibernate.jdbc.wrap_result_sets" value="false"/>
<property name="hibernate.query.jpaql_strict_compliance"
value="false"/>
<property name="hibernate.ejb.interceptor" value="MyInterceptor"/>
<!-- Hibernate Search Properties -->
<property name="hibernate.search.lucene_version" value="LUCENE_35"/>
<property name="hibernate.search.default.directory_provider"

<property name="hibernate.search.default.batch.merge_factor"

<property name="hibernate.search.default.batch.max_buffered_docs"
value="100"/>
<property name="hibernate.search.​default.​exclusive_index_use"

<property name="hibernate.search.default.reader.strategy"

</properties>
</persistence-unit>
