• Ruby 2.4 introduces report_on_exception to control if it reports exceptions in thread, this default value has been false in Ruby 2.4.

Refer https://www.ruby-lang.org/en/news/2016/11/09/ruby-2-4-0-preview3-released/

• Ruby 2.5 changes report_on_exception default value to true since this commit https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?revision=61183&view=revision

This pull request suppresses expected exceptions by setting report_on_exception = false it also supports Ruby 2.3 which does not havereport_on_exception.
