* Upgradle JUnit to 4.13
Removed third_party/junit folder and all usage of the
JunitBackPort class. As a result, third_party is no
longer a Gradle subproject.
Minor code changes were needed to work around an
error-prone pattern: multiple statement in assertThrows'
runnable lambda.
Also third_party/activation and third_party/jsch. These
dependencies are loaded from remote maven repo. The local
copies are not in use.
* Upgrade to Truth 1.0
Refactored fail(...) to assertWithMessage().fail().
Upgraded com.google.monitoring-client family of dependencies to 1.0.6
Also fixed bad use of io.StringIO (on binary buffer) recently introduced to
google-java-format-diff.py.
* Fix dependency-locking config
Reenable dependency locking after a bug errorneouly turned it off.
Removed the guava-related workaround that forcefully resolve to
the -jre distribution.
Enabled locking for buildSrc by updating its property file.
Updated all lock files.
