jclouds master branch now requires Java 7, which we expect to release as 2.0. We upgraded to narrow the compatibility matrix which we support and to allow use of new language and library features, including try-with-resources, NIO.2, and HTTP client improvements. We previously discussed this upgrade on the user mailing list:

Please report any issues with this upgrade at: https://issues.apache.org/jira/browse/JCLOUDS-652 -- Andrew Gaul http://gaul.org/
