new 257c216 ISSUE #230: Enable checkstyle for more packages
257c216 is described below
commit 257c21630ab93b6adccbf955899451bd550a1d07
Author: Aaron Coburn <[email protected]>
AuthorDate: Sat Dec 2 19:47:01 2017 +0800
ISSUE #230: Enable checkstyle for more packages
Part of #230, this enables the checkstyle plugin for the `replication` and
`server.http.service` packages.
Descriptions of the changes in this PR:
Most of the changes here are merely cosmetic. The only change of any
significance is in the `RecoveryBookieService.RecoveryRequestJsonBody` class in
which the JSON object fields had to be changed in order to conform to the
Checkstyle rules: `bookie_src` to `bookieSrc` and `delete_cookie` to
`deleteCookie`. Using a Jackson annotation (`JsonProperty`), however, means
that these field names continue to be parsed and serialized as `bookie_src` and
`delete_cookie`, respectively.

This closes #800 from acoburn/checkstyle_replication, closes #230
