Cause an ArrayIndexOutOfBounds when initialize Regexp
-----------------------------------------------------
Key: JRUBY-2268
URL: http://jira.codehaus.org/browse/JRUBY-2268
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.1RC2, JRuby 1.0.3
Environment: ruby 1.8.6 (2008-02-16 rev 5944) [i386-jruby1.1RC2]
ruby 1.8.5 (2007-12-15 rev 5200) [i386-jruby1.0.3]
Reporter: Tooru TAKAHASHI
Assignee: Thomas E Enebo
Regexp.new throws an ArrayIndexOutOfBoundsException in 1.1RC2 and 1.0.3.
Reason:
RubyRegexp.java l.469 in 1.1RC2 and KCode.java l.55 in 1.0.3
Those may be considered `nil', but unconsidered an empty String
