Bump JDK version to 11.0.2

[ghost]

OpenJDK 11.0.1 seems to have vanished from Oracle's servers.

We hit this in Elasticsearch too: elastic/elasticsearch#37621. We should figure out what to do about 6.6, 6.x, and master since these builds have moved to the elasticsearch repository (so we aren’t duplicating these fixes).

LGTM.
