JRuby with joni breaks hard on some regexps
-------------------------------------------
Key: JRUBY-1646
URL: http://jira.codehaus.org/browse/JRUBY-1646
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: Ubuntu Linux, Latest JRuby 1.1b1 trunk
Reporter: Vladimir Sizikov
Priority: Critical
Try this one:
"blah, 00-06".sub(/\b(\d{2}|\d{4})-(\d{2,3})\b/n, " ")
For me, JRuby throws an exception and terminates:
# jruby -e '"blah, 00-06".sub(/\b(\d{2}|\d{4})-(\d{2,3})\b/n, " ")'
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1

This crash is encountered when trynig to execute MRI's time tests, so it's
pretty important to fix it.
