[JENKINS-16337] ssh-cli-auth 1.4

Added logging to FullDuplexHttpService

(cherry picked from commit 83835770)

The core developers might come to a different consensus to address this
problem, but until then I'm incorporating this change to make sure
future releases can be produced.

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
