@cvrebert the code made here contains a puzzle 1126-bb836510/#1130, which will be resolved soon

[cvrebert]

@yegor256 It seems that @dmarkov has attributed that puzzle to the wrong PR.

[yegor256]

@cvrebert looks like it's your fault :) see https://github.com/jcabi/jcabi-github/blob/master/src/main/java/com/jcabi/github/RtStatuses.java#L121
