Hendy Irawan commented on ARIES-904:
------------------------------------
Probably a useful snippet of the Blueprint XML.
I'm using JPA via EntityManagerFactory (cannot use jpa:context due to
#ARIES-796 ), with CM PropertyPlaceholder as follows :
{code}

Commenting this line:
{code}
<property name="em" ref="magentoEm"/>
{code}
makes the ConcurrentModificationException go away.
