Using Camel 2.14.0, I'm experiencing the exact same situation as
described in this old Jira issue:
https://issues.apache.org/jira/browse/CAMEL-5677 only difference is that
my routes are file (or SFTP) based, not SEDA.
Trying something like:
for (int i = 0; i < 50; i++) {
camelContext.startRoute(routeId);
camelContext.stopRoute(routeId);
}
results in 50 orphan threads of this type:
"Camel (camel) thread #231 - sftp://user@host/path"; #10170 daemon prio=5

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