[Engine-devel] No-arg constructor required by default in backend "common" module's classes

Hi guys, in order to avoid potential errors related to GWT RPC serialization, a recent patch [1] introduced the requirement for no-arg constructor in backend "common" module's classes. [1] http://gerrit.ovirt.org/#/c/21733/ (Even though we're planning to move away from GWT RPC to using REST API, for the time being, this should prevent RPC related errors caused by missing no-arg constructor, which are sometimes hard to trace.) For a select few classes *not* involved in RPC communication, you can add these in checkstyle-suppressions.xml file. Vojtech
