jruby version has just gone to 0.9.1. I'm here at RubyConf 2006 and if you need anything from the developer, he's here until tomorrow. :)

@java: Could you fix metadata.xml please? jruby is not a valid herd...
Bump commited to CVS, thanks for reporting. If you talk to the dev, ask him if he could merge the build.xml patch upstream, and make sources of plaincharset.jar available :) had to use the bundled jar for now.
