This works with previous release Netbeans 6.8 / build-in jruby 1.4. Thus it is a regression.
Checking for netbeans updates with Netbeans 6.9 works fine.
Downloading and installing netbeans plugins with Netbeans 6.9 works fine.
Reporting a netbeans error does not work (socket error), likely due to authentication problems too. (This is another error!)
Gem update via jruby commandline according the following shema works fine:
gem update -p http://username:password@proxyname:portnumber
Gem update via Netbeans GUI works fine
when under Tools->Options->Manual Proxy Setting Proxy the following is intered:
-Http Proxy: http://username:password@proxyname
-Use the same proxy settings for all protocols: yes
-Proxy Requires Authenticiation: no
However in this case checking Netbeans updates and downloading Netbeans plugins fails, as these do not understand the above proxy format.
In Netbeans 6.9 there seems to be a problem when providing proxy authentication setting from Netbeans to jruby gems.
Replace "username", "password", "proxyname", "portnumber" by the applicable values for your firewall.
