Re: ProxySelector2

If NetBeans IDE is not able connect to Internet then you'll not see content
in the "Start Page" tab. This really the best test if NetBeans IDE can
access Internet or not.

I can tell from your log output that your site is using WPAD method to
discover the location of your site's PAC file. (which in your case seems to
reside on your intranet on address http://wpad/wpad.dat). You can actually
download the PAC file and view it as it is plain text JavaScript. Anyway,
in this sense your site is pretty main stream compared to any other
corporate site.

Every time an URL is called NetBeans will evaluate this little JavaScript
file. This is true both with and without the plugin. The plugin improves a
lot on this. Without the plugin PAC file evaluation just doesn't work in NB
if your are using Java 8. As you may be aware Java 8 included a new and
improved JavaScript engine called Nashorn. However this particular piece in
NB core code was made long before Java 8 became available so it was
developed and tested against another JavaScript engine ... and now the code
just doesn't work anymore (bug 245116). The other reason is that the NB
core code in this area doesn't implement all the mandatory PAC JavaScript
functions, say for example the script calls JavaScript function
dnsResolve() (which the PAC standard mandates to exist, and guess what:
many, many PAC scripts out there indeed calls this function) then the proxy
resolution will silently fail in NB core, that is if you are NOT using the
plugin.  Ok, I'll stop with the reasons why you should be using the plugin.
:-)

Anyway, to get closer to a resolution you'll need to enable some logging.
Go to your NetBeans IDE installation directory and locate the file
etc/netbeans.conf. Now edit the "netbeans_default_options" variable so that
you append to it as follows:

netbeans_default_options="........
-J-Dorg.netbeans.core2.network.proxy.level=FINEST"

Make sure the plugin is installed. Restart your IDE and wait 1-2 minutes
and then post all relevant lines from messages log here. Those lines
relevant would all be containing "org.netbeans.core2.network.proxy".

If you want - out of curiosity - to do the same but WITHOUT the plugin
(i.e. using bare NetBeans) then it would be
"org.netbeans.core.network.proxy.level=FINEST" instead but core NB code
does less logging than my plugin. Still helpful though.
