100% coverage always reported on jruby 1.6.7 in 1.9 mode

[pangloss]

When I view the files in the html output, it is easy to see that the coverage number is wrong. For instance one 60-line source file has only one line covered, but the stats I get for the file are

100.0 % covered
1 relevant lines. 1 lines covered and 0 lines missed.

In all cases, only covered lines are counted as relevant.

I'm running JRuby with the --debug flag to ensure that full tracing functionality is enabled:

COVERAGE=1 jruby --debug bin/rspec

I'm having the same issue here

I'm also having the same problem, who can help us resolve it? thanks

Although JRuby recently added a coverage library similar to MRI's one, it currently simply does not work. There already is an open issue for tracking JRuby support, #86. You can find further details and links on this topic over there. Closing this as duplicate.
