Description
Summary
When JIRA generates many cache flush events (see JRASERVER-64839), flushes for activeUsersCountForLicense cache are blocking and stack (wait) for each other.
Expected Results
Caches are not blocking
Actual Results
Thread dump, thread trying to flush the cache: com.atlassian.cache.ehcache.LoadingCache.removeAll
