> Key: JCR-3627
> URL: https://issues.apache.org/jira/browse/JCR-3627
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core
> Affects Versions: 2.6.2
> Environment: Debian/GNU Linux 7.1 on x86-64
> Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
> Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
> Apache Tomcat 7.0.41
> Reporter: Maxim Zinal
> Attachments: tomcat-details.log
>
>
> An application contains embedded JackRabbit repository, configured via custom
> Spring beans.
> After a proper application shutdown (which includes a proper shutdown of
> JackRabbit repository by calling RepositoryImpl.shutdown() method), Tomcat
> prints lots of the following messages:
> jul 23, 2013 4:55:48 PM org.apache.catalina.loader.WebappClassLoader
> clearReferencesThreads
> SEVERE: The web application [/demoapp] appears to have started a thread named
> [jackrabbit-pool-23] but has failed to stop it. This is very likely to create
> a memory leak.
> A typical thread dump of those threads looks like this:
> sun.misc.Unsafe.park(Native Method)
> java.util.concurrent.locks.LockSupport.park(LockSupport.java:186)
>
> java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2043)
>
> java.util.concurrent.ScheduledThreadPoolExecutor$DelayedWorkQueue.take(ScheduledThreadPoolExecutor.java:1085)
>
> java.util.concurrent.ScheduledThreadPoolExecutor$DelayedWorkQueue.take(ScheduledThreadPoolExecutor.java:807)
>
> java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:1068)
>
> java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1130)
