`Connection.inetAddress()` fails for IPv6 addresses

[angusholder]

Here's a minimal repro

package com.example

import com.ngrok.Connection
import com.ngrok.Listener
import com.ngrok.Session

fun main() {
    val session: Session = Session.withAuthtoken("...").connect()

    session.use {
        val listener: Listener.Edge = session.edge()
            .label("edge", "...")
            .listen()

        listener.use {
            while (true) {
                // Accept a new connection
                val conn: Connection.Edge = listener.accept()

                println("conn.getRemoteAddr() = ${conn.remoteAddr}")
                println("conn.inetAddress() = ${conn.inetAddress()}") // Crashes
            }
        }
    }
}

And the log output from running it

conn.getRemoteAddr() = [2a00:23c8:a8dd:e501:b02c:ea1a:83cf:395e]:64440

Hi @angusholder ,

Thanks for using ngrok-java and reporting this issue. Indeed, we should be using the last column : as a divider between the host and the port of an address, before passing it to InetAddress to create one. Therefore, I've created a PR #31 that amends the logic to do so. Don't hesitate to reach out if you have any other issues or comments with our library.

Thanks!

@angusholder - we've released v0.4.1 which contains the above fix. Thanks for reporting!
