The proposed 8.0.22 release is:

- Crawled all links (except /manager, /host-manager and

- Smoke tests of BIO, NIO, NIO2 and APR, with and without TLS. Only
NIO2+TLS fails.

I smoke tested with this crawler:

I get in the logs some of those:

I probably won't be able to do any more tests before Monday.
I have done some tests with jmeter. Calling the "home" page of tomcat
through TLS with the different connectors BIO, NIO and NIO2. Using 100
concurrent "clients" and letting each client repeat 1000 requests, I get
the following results:
* NIO and BIO run without errors.
* NIO2 seems to run OK at first, but after a while (last test the
"while" ended after 17900 requests) jmeters threads will not get a
response from tomcat. The test will continue when the clients timeout
after 60 seconds.
I see no errors in tomcat logs. The access logs show a time jump of one
minute:

If I repeat the same tests with 8.0.21 the test will run without delay
(or timeout on jmeter side).
Without encryption all connectors will complete the tests without delay
on 8.0.22.
This looks to be the culprit:
http://svn.apache.org/viewvc?view=revision&revision=1672626
Looks to be OK, when I revert that patch on the 8.0.22. NIO2 with TLS
completes without delay.
