I have a freshly installed NetBeans 8.0.2 release.
When I try to update plugins I get a "Networking problem" and a suggestion to check my proxy settings.

I am behind a corporate proxy and my proxy settings are set to "Use System Proxy Settings". When i press "Test connection" after a while I get an exclamation mark near the button saying "Connection failed (null)" on hover.

The NetBeans log file contains no exceptions or errors just INFO messages from INFO [org.netbeans.core.network.proxy.NetworkProxyReloader]
When I press the "Reload" button on proxy configuration page the NetBeans log file is updated with a few messages from [org.netbeans.core.network.proxy.NetworkProxyReloader]. When I try the "Test connection" button nothing is appended to the log.

Switching to manual proxy setting does not help.
Using the -J-Djava.net.preferIPv4Stack=true config option does not help.
