Martin Meinhold created HTTPCLIENT-1298:
-------------------------------------------
Summary: Unable to shutdown executor service used by
AsynchronousValidator
Key: HTTPCLIENT-1298
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1298
Project: HttpComponents HttpClient
Issue Type: Bug
Components: Cache
Affects Versions: 4.2.3
Reporter: Martin Meinhold
Currently there is no way to tell the CachingHttpClient to shutdown the
executor service used by its AsynchronousValidator. This could lead to a
resource leak, but probably only in cases when the threads weren't reclaimed by
the thread pool. So only when it is actually processing tasks. As long as the
thread pool isn't used, it won't create threads.
>From an application life-cycle point of view there should be a way to
>explicitly tell the HttpClient to shutdown and release all resources now
>regardless whether there are any outstanding validation requests or not.
I have a patch against version 4.2.1 which in fact adds a shutdown() method to
the HttpClient and the AsynchronousValidator. Today I saw, there is already a
CloseableHttpClient. So do you need any contribution to fix this? Looks like
there is already a plan for that.
Btw: thanks for already supporting the background validation via the
stale-while-revalidate header.
