[jira] [Commented] (PROTON-1519) qpid_proton 0.17.0 Ruby gem does
not work with Ruby 2.4.1
[ https://issues.apache.org/jira/browse/PROTON-1519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16091731#comment-16091731 ]
Jason Frey commented on PROTON-1519:
------------------------------------
I think I see the issue. In Ruby 2.4, Fixnum and Bignum classes have been merged into the Integer class. The code is [created a mapping https://github.com/apache/qpid-proton/blob/10df4133e8877ee535e24b494738356369dcd24c/proton-c/bindings/ruby/lib/codec/mapping.rb#L99] for both classes but Ruby resolves those classes to the same class. When [placed into the Hash https://github.com/apache/qpid-proton/blob/10df4133e8877ee535e24b494738356369dcd24c/proton-c/bindings/ruby/lib/codec/mapping.rb#L55], the code see a duplicate and fails.
I'll put in a pull request for this fix as it seems pretty straightforward.
