------------------------------------

Hi,

I'm having the same issue with the following configuration and would like to know, whether this case is also fixed or no:

I'm using own infinispan configuration (not AS7 infinispan subsystem) for Hibernate 2LC.

My Infinispan configuration is:

<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:infinispan:config:5.1" xsi:schemaLocation="urn:infinispan:config:5.1 http://www.infinispan.org/schemas/infinispan-config-5.1.xsd">
    <global>
        <globalJmxStatistics enabled="true" jmxDomain="infinispan" allowDuplicateDomains="true" />
    </global>
  .......
</infinispan>

My persistence.xml file contains the following line:

<property name="hibernate.cache.region_prefix" value="test"/> or <property name="hibernate.cache.region_prefix" value=""/>

Following happens: when the server is started and I'm deploying the real app using maven jbossas plugin, the following exception occurs: http://pastie.org/4317161

The thing is that, if I'm starting already deployed server (with the config described above), the exception doesn't occur and the app is accessible via browser. If I'm redeploying app with jboss-as-maven-plugin, then the exception again occurs and the app is not accessible any more.

The removal of <globalJmxStatistics /> tag fixes the problem. 

My Environment: Jboss AS 7.1.1, JDK 1.7.0_04

Thanks in advance.

Regards,
Anna.
