(Regexp Regression) JRuby with Joni calculates String#rindex incorrectly in
some cases
--------------------------------------------------------------------------------------
Key: JRUBY-1656
URL: http://jira.codehaus.org/browse/JRUBY-1656
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.x
Environment: Latest JRuby 1.1b from trunk.
Reporter: Vladimir Sizikov
Assignee: Thomas E Enebo
This is funny:
("c" + "x" * 100).rindex(/cx/) ==> nil
but
("c" + "x" * 99).rindex(/cx/) ==> 0
(the only difference between two strings is 99 'x'es instead of 100)
In MRI, and in earler JRuby without Joni, the result is always 0.
