[jboss-user] [JBoss Cache Users] - InstanceAlreadyExistsException During hot deployment

I am currently using JBOSS Cache v3.3.1GA with Websphere 6.1.0.21, JPA, Hibernate3.3, Spring 2.5.6. During development, we have hot deployed the application. So whever I make any change in the java code, code gets hot deployment on the server and I get the exception javax.management.InstanceAlreadyExistsException. | javax.management.InstanceAlreadyExistsException: jboss.cache:service=TreeCache-Cluster,cell=TD2471Node01Cell,node=TD2471Node01,process=server1 | at com.sun.jmx.mbeanserver.RepositorySupport.addMBean(RepositorySupport.java:470) | at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.internal_addObject(DefaultMBeanServerInterceptor.java:1428) | at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.registerObject(DefaultMBeanServerInterceptor.java:954) | at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.registerMBean(DefaultMBeanServerInterceptor.java:355) | at com.sun.jmx.mbeanserver.JmxMBeanServer.registerMBean(JmxMBeanServer.java:515) | at com.ibm.ws.management.PlatformMBeanServer.registerMBean(PlatformMBeanServer.java:472) | at org.jboss.cache.util.MBeanConfigurator.registerInterceptors(MBeanConfigurator.java:72) | at org.jboss.cache.TreeCache._createService(TreeCache.java:1385) | at org.jboss.cache.TreeCache.startService(TreeCache.java:1463) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:272) | at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:173) | at org.hibernate.cache.TreeCacheProvider.start(TreeCacheProvider.java:75) | When I restart the server, it starts working fine. This process goes on whever we make any code change. Any help/clue with be highly appreciated. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4257137#...
