As long as the CM are created through TestCacheManagersFactory, this should will soon not be an issue: https://jira.jboss.org/jira/browse/ISPN-314

Alternatively, if you have a unit test that needs to create its own CacheManager directly, please use TestCacheManagerFactory [3].  Do *not* use "new DefaultCacheManager()" directly since this means the framework does not have a chance to alter config settings to work within the framework, including clustering settings to make sure the test does not interfere with other tests, threadpool settings to prevent unnecessary OOMs when running the entire suite with thousands of cache managers, etc.
