Description

With Netbeans 12.3 on macOS Big Sur, the proxy settings are seemingly ignored. When trying to e.g. download plugins with a proxy in place, the connection times out.

This works fine in macOS 10.15 (Catalina); however, even on Catalina, the "test connection" button with a proxy in place shows a weird behaviour, a red stop sign and the message "Connection failed (null)", see attached screenshot. But despite this message, the proxy actually works on Catalina, but not on Big Sur.

I've tried this with Oracle JDK 8 and OpenJDK 8, 11 and 16, same result.
