strscan incorrect version #6414
Description
I need to use StringScanner#captures (introduced in MRI 2.5) in rubocop-ast, which is a core dependency of RuboCop.
It appears that the version included in JRuby has it (great!), yet the version states 0.7.0 (same as Ruby 2.4 which doesn't have captures) and adding a >= 1.0.0 dependency in my gemspec will fail on JRuby
Is there a way for me to publish rubocop-ast so that it works with Ruby 2.4 (i.e. by upgrading strscan to >= 1.0.0) and be compatible with JRuby?
Sadly, I already published the gem 😓 (clearly, I need to add JRuby on the CI...), so a quick response would be greatly appreciated.
