In 1.4.0 we used Elasticsearch 2.3.5 and Jackson 2.8. This
combination was incompatible in some circumstances due to a change
in Jackson (gh-6508). With Elasticsearch 2.4 yet to be released at the
time, the only way to restore compatibility was to downgrade Jackson.
With the release of Elasticsearch 2.4 we have another option: revert
the Jackson downgrade and upgrade Elasticsearch instead. While we
normally wouldn't consider upgrading to a new minor version of a
dependency in a maintenance release we have to do something to restore
compatibility. The alternative is to downgrade Jackson but that will
affect more people (Jackson is more widely used than Elasticsearch)
and will lose some functionality that was new in Jackson 2.8 that
people may already be relying upon.
This commit restores the use of Jackson 2.8 – including the
2.8-specific dependency management – and upgrades to Elasticsearch 2.4
Closes gh-6868
As part of the upgrade, Tomcat now requires a keystore to contain
an X.509 certificate. The two stores used in our tests have been
updated by exporting their private keys and adding them as
certificates. For example:
$ keytool -exportcert -keystore test.jks -alias tomcat > exported
$ keytool -importcert -keystore test.jks -file exported

Previously, Spring Data Cassandra excluded Netty from the Cassandra
Driver's dependencies. This was an error that we replicated in
our dependency management. The exclusion has been removed from
Spring Data Cassandra's pom. This commit makes the equivalent update
to our dependency management.
Fixes gh-6616
Closes gh-6721
We've downgraded to 2.7.x so we need to remove the dependency
management for jackson-datatype-jaxrs which is new in Jackson 2.8
Closes gh-6508
