After a quick look at the decompiled code for the method net.minecraft.client.gui.screens.ConnectScreen#connect it seems like in the "generic exception case" the hostname and port are only stripped from the exception if the InetSocketAddress is not null.
The regex to filter the host/port will (probably) also not catch a string in the form of "locahost/127.0.0.1:25565"
