Bug: Unique Endpoints Leaking in DefaultInflightRepository
----------------------------------------------------------
Key: CAMEL-5058
URL: https://issues.apache.org/jira/browse/CAMEL-5058
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.9.0
Reporter: Zach Calvert
If you have an endpoint protocol which uses unique URIs you will leak Strings
in the HashMap stored in the DefaultInflightRepository
(org.apache.camel.impl.DefaultInflightRepository)
It seems there is a reference counting scheme in place, but it doesn't do a
remove until the "stop" method is called to shut the system down. We are
running XMPP endpoints, which use a protocol like
xmpp://someaccount@domain/password?to=someOtherAccount
When there are 10 million accounts, not all of which are active, but all of
which may message at some time or another, no references are removed to the
endpointCount.
When the count becomes 0, the reference should be removed and the size method
will still return the appropriate result.
Please be careful in the implementation to synchronize on some object (perhaps
the AtomicInteger) reflecting a read/write lock on the endpoint count
modification.
