When setting a proxy via JVM arguements (-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=1080), the game completely ignores these and connects directly to the server with no regards to proxy settings.

To reproduce the bug, click Edit Profile on the launcher, and then check "JVM Arguements", and put "-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=9999" in the JVM arguements.

You will notice that if you do not have a SOCKS5 server hosted on 127.0.0.1:9999, that these are invalid proxy settings.

What should happen is that you will not be able to connect to any multiplayer related services, because your proxy settings are invalid.

The actual result is that this proxy is completely ignored and you will still be able to join servers because you are connecting directly, and not through the proxy that was set by the JVM arguements.
