Loïc Ledoyen commented on HIBERNATE-134:
----------------------------------------

I faced the same issue, solving it by using a custom factory, here is the code I used :
{code:title=persistence.xml|borderStyle=solid}
...
<property name="hibernate.cache.region.factory_class" value="org.jboss.as.jpa.hibernate4.infinispan.JndiInfinispanRegionFactory" />
...
{code}

{code:title=JndiInfinispanRegionFactory.java|borderStyle=solid}
package org.jboss.as.jpa.hibernate4.infinispan;

import java.security.AccessController;
import java.security.PrivilegedAction;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

import org.hibernate.cache.CacheException;
import org.hibernate.cache.infinispan.util.CacheCommandFactory;
import org.infinispan.AdvancedCache;
import org.infinispan.commands.module.ModuleCommandFactory;
import org.infinispan.factories.GlobalComponentRegistry;
import org.infinispan.manager.EmbeddedCacheManager;

/**
 * Put in modules/org/jboss/as/jpa/hibernate/4
 * Takes advantages of the classic {@link org.hibernate.cache.infinispan.JndiInfinispanRegionFactory, but adding the CacheCommandFactory to solve classloading issue HIBERNATE-134
 */
public class JndiInfinispanRegionFactory extends org.hibernate.cache.infinispan.JndiInfinispanRegionFactory {

    private static final long serialVersionUID = -3849525520794104001L;

    public JndiInfinispanRegionFactory() {
		super();
    }

    public JndiInfinispanRegionFactory(Properties props) {
		super(props);
    }

    @Override
    protected EmbeddedCacheManager createCacheManager(Properties properties) throws CacheException {
		EmbeddedCacheManager manager = super.createCacheManager(properties);

		CacheCommandFactory ccf = new CacheCommandFactory();
		// ccf.setRegionFactory(this);
		for (String cacheName : manager.getCacheNames()) {
			GlobalComponentRegistry globalCr = manager.getCache(cacheName).getAdvancedCache().getComponentRegistry().getGlobalComponentRegistry();
			Map<Byte, ModuleCommandFactory> factories = (Map<Byte, ModuleCommandFactory>) globalCr.getComponent("org.infinispan.modules.command.factories");
			if (factories == null || factories.size() == 0) {
				factories = new HashMap<Byte, ModuleCommandFactory>();
				factories.put((byte) 'a', ccf);
				globalCr.registerComponent(factories, "org.infinispan.modules.command.factories");
			}
		}
		return manager;
    }

    @SuppressWarnings("rawtypes")
    @Override
    protected AdvancedCache createCacheWrapper(AdvancedCache cache) {
		PrivilegedAction<ClassLoader> action = new PrivilegedAction<ClassLoader>() {
			public ClassLoader run() {
				return Thread.currentThread().getContextClassLoader();
			}
		};
		return cache.with(AccessController.doPrivileged(action));
    }
}
{code}

Then I packaged this class in some jar and added it to the module *org/jboss/as/jpa/hibernate/4*

Hope this will help.

> We use Infinispan as 2LC for Hibernate in a clustered configuration under JBoss 7. So {{persistence.xml}} contains the following line: {code:xml}<property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.infinispan.InfinispanRegionFactory"/>{code}.

> This issue takes place because context {{ClassLoader}} is substituted in {{org.hibernate.ejb.Ejb3Configuration#configure}}. So Infinispan can not find {{org.infinispan.commands.module.ModuleCommandExtensions}} realization from {{hibernate-infinispan}} module in {{org.infinispan.util.ModuleProperties#loadModuleCommandHandlers}} method.
