Expected Behavior

Calling Coverage.line_stub should work, but it is undefined.

Actual Behavior

This method isn't defined in JRuby.

notes

This is defined here in CRuby: https://github.com/ruby/ruby/blob/c5eb24349a4535948514fe765c3ddb0628d81004/ext/coverage/lib/coverage.rb

Given it is just Ruby, I can work around this, but just adding that extension when running JRuby

require 'coverband/utils/jruby_ext' if RUBY_PLATFORM == 'java'

but I wanted to let you know, as I am not sure if that is something you would want to just directly support @headius

Creating a new issue, as this follows up on a closed out ticket, #3096
