(cherry picked from commit 72901698)

Use rerunFailingTestsCount rather than @RandomlyFails
(cherry picked from commit c54c363b)

Due to the switch to Java8, this issue that was previously non-blocking
is now a release blocker. We generally don't check that the trunk is
javadoc error safe, so requiring that only during the release process is
likely going to cause this same problem over and over again

And suppress associated workaround

[FIXED JENKINS-33595] Picks up https://github.com/jenkinsci/sshd-module/pull/11
to turn off SSHD by default, but expose it to tests which wish to enable it.

Allow http://repo.jenkins-ci.org/public/org/jenkins-ci/modules/sshd/1.11-SNAPSHOT/sshd-1.11-20170315.153852-1.jar to be downloaded.

* [FIXES JENKINS-42371] - Update remoting to 3.6

Fixed issues:

* [JENKINS-42371](https://issues.jenkins-ci.org/browse/JENKINS-42371) - Properly close the `URLConnection` when parsing connection arguments from the JNLP file. It was causing a descriptor leak in the case of multiple connection attempts. ([PR #152](https://github.com/jenkinsci/remoting/pull/152))

* Remoting 3.6 has been burned

(cherry picked from commit b6e4fb4b)

https://github.com/jenkinsci/remoting/edit/master/CHANGELOG.md

Fixed issues:

* [JENKINS-40710](https://issues.jenkins-ci.org/browse/JENKINS-40710) - Match headers case-insensitively in `JnlpAgentEndpointResolver` in order to be compliant with HTTP2 lower-case headers. ([PR #139](https://github.com/jenkinsci/remoting/pull/139), [PR #140](https://github.com/jenkinsci/remoting/pull/140))
* [JENKINS-41513](https://issues.jenkins-ci.org/browse/JENKINS-41513) - Prevent `NullPointerException` in `JnlpAgentEndpointResolver` when receiving a header with `null` name. ([PR #140](https://github.com/jenkinsci/remoting/pull/140))
* [JENKINS-41852](https://issues.jenkins-ci.org/browse/JENKINS-41852) - Fix exported object pinning logic to prevent release due to the integer overflow. ([PR #148](https://github.com/jenkinsci/remoting/pull/148))

Improvements:

* [JENKINS-41730](https://issues.jenkins-ci.org/browse/JENKINS-41730) - Add the new `org.jenkinsci.remoting.engine.JnlpAgentEndpointResolver.ignoreJenkinsAgentProtocolsHeader` property, which allows specifying a custom list of supported protocols instead of the one returned by the Jenkins master. ([PR #146](https://github.com/jenkinsci/remoting/pull/146))
* Print the Filesystem Jar Cache directory location in the error message when this cache directory is not writable. ([PR #143](https://github.com/jenkinsci/remoting/pull/143))
* Replace `MimicException` with the older `ProxyException` when serializing non-serializable exceptions thrown by the remote code. ([PR #141](https://github.com/jenkinsci/remoting/pull/141))
* Use OID of the `ClassLoaderProxy` in error message when the proxy cannot be located in the export table. ([PR #147](https://github.com/jenkinsci/remoting/pull/147))

(cherry picked from commit 815da8aa)

With Java 8 set as build target version.
