             Summary: RemoteSpringSessionTest random failures
                 Key: ISPN-7160
                 URL: https://issues.jboss.org/browse/ISPN-7160
             Project: Infinispan
          Issue Type: Bug
          Components: Spring Integration
            Reporter: Dan Berindei
            Assignee: Sebastian Łaskawiec
            Priority: Critical
             Fix For: 9.0.0.Beta1


{{RemoteSpringSessionTest}} and {{EmbeddedSpringSessionTest}} use the default cache jmx configuration, so they try to register the same JMX object names. If they run in parallel, one of them will fail to start the cache manager:

{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.integrationtests.spring.boot.session.remote.RemoteSpringSessionTest.beforeclass(RemoteSpringSessionTest.java:29)
{noformat}

If the cache manager was not created, teardown also fails with a NPE:

{noformat}
java.lang.NullPointerException
at org.infinispan.integrationtests.spring.boot.session.remote.RemoteSpringSessionTest.afterClass(RemoteSpringSessionTest.java:41)
{noformat}

The test should use the {{TestCacheManagerFactory}} methods to create the cache manager, which will set a unique JMX domain name for each instance.
