Bump the jetty version to 9.2.15.v20160210
Upgrade jetty-server dependency
Fixed in https://git1-us-west.apache.org/repos/asf?p=calcite.git;a=commit;h=dcfbc4a543a10b902f2a6d15e524953beb76da3e and https://git1-us-west.apache.org/repos/asf?p=calcite.git;a=commit;h=ce8059847474fef5bf5c99fd7efbd30ca29ae8dd, for 1.7.1 and 1.8.0, respectively.
Will be fixed in Calcite version 1.7.0 by virtue of Calcite no longer including Jetty directly, but including it indirectly via Avatica 1.7.1. Calcite versions 1.1 - 1.6 inclusive have this problem.
I was mistaken. Calcite will continue to need Jetty, because its Spark adapter depends on it. In http://git-wip-us.apache.org/repos/asf/incubator-calcite/commit/1567ca7, we have upgraded Jetty to 9.2.15.v20160210, the same version used by Avatica 1.7.1.
Resolved in release 1.7.0 (2016-03-22).
