Unable to tunnel through proxy. Proxy returns “HTTP/1.1 407” via https
You have to edit the variables
jdk.http.auth.tunneling.disabledSchemes and jdk.http.auth.proxying.disabledSchemes to blank like this:
jdk.http.auth.tunneling.disabledSchemes=
jdk.http.auth.proxying.disabledSchemes=
In my case I found in this file
jdk1.8.0_111/jre/lib/net.properties
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.

Your options:
- solve the issue (for the sake of security) by upgrading the authentication scheme of your proxy, e.g. to Digest access authentication
or just workaround the issue by running Java with
java -Djdk.http.auth.tunneling.disabledSchemes=""
This may be helpful:
System.setProperty("jdk.http.auth.tunneling.disabledSchemes", "false");
System.setProperty("jdk.http.auth.proxying.disabledSchemes", "false");
