--------------------------------------

             Summary: Starting and stopping routes leak threads
                 Key: CAMEL-8146
                 URL: https://issues.apache.org/jira/browse/CAMEL-8146
             Project: Camel
          Issue Type: Bug
    Affects Versions: 2.14.0
            Reporter: Bjørn Ellingsen
            Priority: Minor
             Fix For: 2.14.1


Seems to be identical consequence as with previous issue CAMEL-5677, but 
perhaps due to a different cause.

Having a file or SFTP based route, trying something like:
{code}
for (int i = 0; i < 50; i++) {
    camelContext.startRoute(routeId);
    camelContext.stopRoute(routeId);
}
{code}
results in 50 orphan threads of this type:

{code}

{code}

Switching to suspend/resume solves the problem, however I guess the start/stop 
issue should be addressed.
