Ruby 1.8 compatibility: /#{/\w/}/uo does not work as expected
-------------------------------------------------------------
Key: JRUBY-4037
URL: http://jira.codehaus.org/browse/JRUBY-4037
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.3.1
Environment: Mac OS X
Reporter: Kornelius Kalnbach
JRuby gives me different results than Ruby 1.8.6 (and 1.8.7) here:
~/ruby/coderay ruby -e 'p "ä"[/#{/\w/}/uo]'
"\303\244"
~/ruby/coderay jruby -e 'p "ä"[/#{/\w/}/uo]'
nil
~/ruby/coderay jruby -v
jruby 1.3.1 (ruby 1.8.6p287) (2009-09-08 6586) (Java HotSpot(TM) 64-Bit Server
VM 1.6.0_15) [x86_64-java]
The problem seems to be that /o somehow treats the embedded regexp differently.
