Issue with jruby and cucumber step with 4 parameters


#1

Hi - sorry for the cross-list post, but this issue happens only with
cucumber and jruby, and I’m not 100% sure which has the problem. It
doesn’t happen with non-j ruby though.
Versions:
cucumber 0.2.3
jruby 1.2.0 on Ubuntu amd64

When I have a cucumber feature with a “Then” step: (well, really it’s
an “And” step):
And the association between “oh” and “apf” has an active adpoint
named “ap” with id “7890”
which translates to the ruby code:
Then /^the association between “(.)" and "(.)” has an active
adpoint named “(.)" with id "(.)”$/ do |arg1,arg2, arg3, arg4|
# nothing needed here to cause the problem…
end

In JRuby (with --backtrace enabled), I get:
And the association between “oh” and “apf” has an active adpoint
named “ap” with id “7890” #
test/features/step_definitions/migration_steps.rb:122
wrong # of arguments(4 for 3) (ArgumentError)

In the normal ruby version of cucumber, this works fine.

I looked at the specific code line, but it’s just a call to:
instance_exec(*args, &block)

Does JRuby have a problem with large numbers of regexp capture groups?
Or is there something else going on here?
