If we warn the user, it is a feature, not a CVE. If your IT department requires you to use an authenticated proxy, you probably won't have a chance to change their thinking.
The problem is, that the JDK at least partitially uses aggressive caching of the property:
https://github.com/openjdk/jdk/blob/47b1c51bbd28582d209db07052e553a76acced65/src/java.net.http/share/classes/jdk/internal/net/http/common/Utils.java#L260-L274
So if you want to make that dynamic you have to reflect into an internal module.

Ah, very true, I didn't notice you were already setting user/password.
What kind of proxy authentication are you using, @shoblingr ? Is it basic, NTLM or what?

Hi, it basic authentication (Proxy-Authenticate: BASIC realm="Auth_LDAP"). I did some tests using jmeter to pass through the proxy. Using java sampler implementation, I have the same behavior than netbeans :

Hi @shoblingr ,
You're getting an HTTP 407 "Proxy Authentication Required" (https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/407)
- Click the "More..." button at the right of the "Manual Proxy Settings".
- Check the "Proxy Requires Explicit Authentication"
- The "Advanced Proxy Options" dialog appears, enter the username and password that you need for that proxy.

Interesting: I just saw this info for the JMeter Java Sampler vs HttpClient4:
There is a bug in the handling of HTTPS via a Proxy (the CONNECT is not handled correctly). See Java bugs 6226610 and 6208335.

I'll risk a guess: Your password (or the username) contains characters outside the ASCII range. If I remember correctly Basic Auth was only defined for Latin1, but was extended to UTF-8 . Do you have the option to test with a password containing only ASCII characters?

we could add a hint to the proxy settings window explaining that a flag might be required to get legacy auth behavior back.
Accessing JDK internals should only be used as last resort IMO. Ideally we should try to shrink the --add-opens list if possible.

Ok I found a solution :)
Following this article : https://stackoverflow.com/questions/41505219/unable-to-tunnel-through-proxy-proxy-returns-http-1-1-407-via-https
It seems the problem is comming from:
_Change in Java 8 Update 111:
Now, proxies requiring Basic authentication when setting up a tunnel for HTTPS will no longer succeed by default. If required, this authentication scheme can be reactivated by removing Basic from the jdk.http.auth.tunneling.disabledSchemes networking property, or by setting a system property of the same name to "" ( empty ) on the command line._
To fix the issue, I added the option -Djdk.http.auth.tunneling.disabledSchemes="" to netbean conf as follow:
netbeans_default_options="-J-XX:+UseStringDeduplication -J-Xss2m **-J-Djdk.http.auth.tunneling.disabledSchemes=\\"\\" ** -J-Dapple.laf.useScreenMenuBar=true (...)
Now it works great :)
Maybe this conf could be added by default in netbean distribution ?
Thanks for your help!

Doesn't that amount to disabling a security feature of the JDK by default? In which case, probably not. Better error message maybe? Also see https://bugzilla.redhat.com/show_bug.cgi?id=1386103

netbeans_default_options="-J-XX:+UseStringDeduplication -J-Xss2m -J-Djdk.http.auth.tunneling.disabledSchemes=\\"\\" -J-Dapple.laf.useScreenMenuBar=true (...)
Now it works great :)
Maybe this conf could be added by default in netbean distribution ?
Thanks for your help!

[GitHub] [netbeans] shoblingr commented on issue #3748: Proxy authentication is not working

Ok I found a solution :)
Following this article : https://stackoverflow.com/questions/41505219/unable-to-tunnel-through-proxy-proxy-returns-http-1-1-407-via-https
It seems the problem is comming from:
_Change in Java 8 Update 111:
Now, proxies requiring Basic authentication when setting up a tunnel for HTTPS will no longer succeed by default. If required, this authentication scheme can be reactivated by removing Basic from the jdk.http.auth.tunneling.disabledSchemes networking property, or by setting a system property of the same name to "" ( empty ) on the command line._
To fix the issue, I added the option -Djdk.http.auth.tunneling.disabledSchemes="" to netbean conf as follow:
etbeans_default_options="-J-XX:+UseStringDeduplication -J-Xss2m **-J-Djdk.http.auth.tunneling.disabledSchemes=\"\"** -J-Dapple.laf.useScreenMenuBar=true (...)
Now it works great :)
Maybe this conf could be added by default in netbean distribution ?
Thanks for your help!

Interesting: I just saw this info for the JMeter Java Sampler vs HttpClient4:
There is a bug in the handling of HTTPS via a Proxy (the CONNECT is not handled correctly). See Java bugs 6226610 and 6208335.

I created this PR for the website explaining the problem https://github.com/apache/netbeans-website/pull/592
Maybe we can add a link to this page from the dialog, so users can learn about the problem (and the solution) in the future.

Hi @shoblingr ,
You're getting an HTTP 407 "Proxy Authentication Required" (https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/407)
- Click the "More..." button at the right of the "Manual Proxy Settings".
- The "Advanced Proxy Options" dialog appears
- Check the "Proxy Requires Explicit Authentication"
- Enter the username and password that you need for that proxy.
