Github user jbertram commented on the issue: https://github.com/apache/activemq-artemis/pull/573 The issue with the threads is that org.apache.directory.server.core.integ.FrameworkRunner which is being used for @RunWith is managing the LDAP server and I believe by the time the thread check executes the LDAP server hasn't been shutdown completely. If we want to keep the thread checker then I think we'll have to find another way to manage the LDAP server.
