type ${type} is not compatible with address ${sa}

Error message

type ${type} is not compatible with address ${sa}

What it means

This Proxy is a local reimplementation of java.net.Proxy restricted to authenticated proxies: the constructor requires type != DIRECT and sa instanceof PasswdInetSocketAddress, echoing the JDK wording 'type ... is not compatible with address'. Because a null address also fails the instanceof check, constructing with no SocketAddress throws the same way.

Solutions

1. Build the address first via PasswdInetSocketAddress.createUnresolved(host, port, user, pass) and pass that to the Proxy
2. Use Proxy.NO_PROXY for direct connections instead of Type.DIRECT
3. Never feed raw InetSocketAddress or other SocketAddress subclasses into this constructor

Example fix

// before
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(host, port)); // throws

// after
PasswdInetSocketAddress addr =
        PasswdInetSocketAddress.createUnresolved(host, port, user, pass);
Proxy proxy = new Proxy(Proxy.Type.HTTP, addr);

if (type == Proxy.Type.DIRECT || !(sa instanceof PasswdInetSocketAddress)) {
    // use Proxy.NO_PROXY for direct, or wrap host/port/credentials first
}
Proxy proxy = new Proxy(type, sa);

static boolean isCompatible(@Nullable Proxy.Type type, @Nullable SocketAddress sa) {
    return type != null && type != Proxy.Type.DIRECT && sa instanceof PasswdInetSocketAddress;
}

When it happens

Trigger: Passing a plain java.net.InetSocketAddress (no credentials) to this Proxy; constructing Proxy(Type.DIRECT, address), where direct connections are meant to be represented by Proxy.NO_PROXY; passing null sa.

Common situations: Mixing system java.net proxy objects with this custom class; porting java.net.Proxy code that tolerated DIRECT-with-address patterns; forgetting to wrap host/port/credentials into PasswdInetSocketAddress before building the Proxy.
