Unclosed threads in Jackrabbit
------------------------------

                 Key: JCR-2836
                 URL: https://issues.apache.org/jira/browse/JCR-2836
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
            Reporter: Jukka Zitting
            Assignee: Jukka Zitting


The Tomcat integration test added in JCR-2831 shows the following warnings 
about Jackrabbit threads that remain in place even after the repository has 
been closed:

08-Dec-2010 12:14:58 org.apache.catalina.loader.WebappClassLoader 
clearReferencesThreads
SEVERE: The web application [] appears to have started a thread named [Timer-1] 
but has failed to stop it. This is very likely to create a memory leak.
08-Dec-2010 12:14:58 org.apache.catalina.loader.WebappClassLoader 
clearReferencesThreads
SEVERE: The web application [] appears to have started a thread named 
[DynamicPooledExecutor] but has failed to stop it. This is very likely to 
create a memory leak.
08-Dec-2010 12:14:58 org.apache.catalina.loader.WebappClassLoader 
clearReferencesThreads
SEVERE: The web application [] appears to have started a thread named [Timer-2] 
but has failed to stop it. This is very likely to create a memory leak.

It would be best to close all such background threads even if they are 
singleton daemon threads and thus unlikely to cause trouble when left 
unattended.
