Andrew Gaul commented on JCLOUDS-1101:
--------------------------------------
I experimented with Java 9+181 and compatibility improved since previous
versions. Changes required:
* add java.xml.bind to modules and require a newer Java
* upgrade to error-prone 2.0.20 and remove stale checkers
* upgrade to maven-enforcer-plugin 3.0.0-M1 and partially remove configuration
It is possible we can enable 1 and 2 via profiles and upgrade to 3 when the
final version releases. See the following branch for changes:
