Thread Problem: Exception in thread ... attempted duplicate class definition..
------------------------------------------------------------------------------
Key: JRUBY-2021
URL: http://jira.codehaus.org/browse/JRUBY-2021
Project: JRuby
Issue Type: Bug
Components: Application Error
Affects Versions: JRuby 1.1RC1
Environment: Windows Server 2003 SP1
java version "1.6.0_04"
Reporter: Douwe Vonk
Attachments: S08test.zip
Looks like writing output via some nested method is causing a problem when more
than one thread is running. Included is a stripped down version of the script.
Just unzip the two files and run.
I get this error:
