ConfigurationOverrideTest random failures ----------------------------------------- Key: ISPN-5481 URL: https://issues.jboss.org/browse/ISPN-5481 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 7.2.1.Final Reporter: Dan Berindei Priority: Critical Fix For: 8.0.0.Alpha2 {{ConfigurationOverrideTest}} uses the default global configuration, and it fails when another test has already registered a cache manager MBean in JMX with the same name: {noformat} org.infinispan.jmx.JmxDomainConflictException: ISPN000034: There's already a JMX MBean instance type=CacheManager,name="DefaultCacheManager" already registered under 'org.infinispan' JMX domain. If you want to allow multiple instances configured with same JMX domain enable 'allowDuplicateDomains' attribute in 'globalJmxStatistics' config element at org.infinispan.jmx.JmxUtil.buildJmxDomain(JmxUtil.java:51) at org.infinispan.jmx.CacheManagerJmxRegistration.updateDomain(CacheManagerJmxRegistration.java:79) at org.infinispan.jmx.CacheManagerJmxRegistration.buildRegistrar(CacheManagerJmxRegistration.java:73) at org.infinispan.jmx.AbstractJmxRegistration.registerMBeans(AbstractJmxRegistration.java:37) at org.infinispan.jmx.CacheManagerJmxRegistration.start(CacheManagerJmxRegistration.java:41) at org.infinispan.manager.DefaultCacheManager.start(DefaultCacheManager.java:625) at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:218) at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:199) at org.infinispan.configuration.ConfigurationOverrideTest.testOverrideWithStore(ConfigurationOverrideTest.java:80) {noformat} We should verify the other tests as well, to make sure they all use the {{PerThreadMBeanServerLookup}} and/or a unique JMX domain.
