Hardy Ferentschik commented on HSEARCH-1026:
--------------------------------------------

This already helped :-)
In case you want to provide a patch, have a look at http://community.jboss.org/wiki/ContributingtoHibernateSearch
All you need is JDK6, git and maven.

Basically you would fork the Search git repo, implement a fix and then create a pull request for it.

Thanks for your help.

> Deploying more than one application using hibernate search with hibernate.search.jmx_enabled=true on the same application server leads to overwrite StatisticsInfoMBean (and probably other mbeans), so exposed statistics will come only from the last deployed application.
> Currently it's impossible to define name of the StatisticsInfoMBean, all created instances are always bound to StatisticsInfoMBean.STATISTICS_MBEAN_OBJECT_NAME = org.hibernate.search.jmx:type=StatisticsInfoMBean.
> From ImmutableSearchFactory:
> {code}
>            if ( isJMXEnabled() ) {
> 			// since the SearchFactory is mutable we might have an already existing MBean which we have to unregister first
> 			if ( JMXRegistrar.isNameRegistered( StatisticsInfoMBean.STATISTICS_MBEAN_OBJECT_NAME ) ) {
> 				JMXRegistrar.unRegisterMBean( StatisticsInfoMBean.STATISTICS_MBEAN_OBJECT_NAME );
> 			}
> 			JMXRegistrar.registerMBean(
> 					new StatisticsInfo( statistics ), StatisticsInfoMBean.STATISTICS_MBEAN_OBJECT_NAME
> 			);
> 		}
> {code}
