Gems fetching failed

Hi,

I am having a problem with the RC releases. When I open the Ruby Gems manager I get an Error dialog box that says:

Gems fetching failed

See troubleshooting section in http://wiki.netbeans.org/RubyGems for help.

Follows output of the gem tool:

*** REMOTE GEMS ***

Error: While executing gem ... (EOFError)
End of file reached

The following works from the command line withou error

jruby -S gem list -r

Should I file a bug? Is there something I can do to stop this from happening
