Personally I'm quite happy with the Golo language. It's a fun language, it has a small run-time library with useful (and, again, fun) features. The JVM needs a small dynamic language like this in my view.
Also, while no work seems to be actively done to migrate Golo to newer Java versions, that's not really a concern to me at this time. For this particular project I plan to stay on Java 8 for the time being. The reason is that I want this program to keep running on my aging and very slow Raspberry pi 1, Model B device, which would otherwise become obsolete to me. It has been running fine for quite some time, monitoring about 3 to 5 players, of various types, each day (I keep not all my players on the network all the time).
Of course, the fact that nobody seems to be actively working on Golo is of some concern, so in the end I may choose to port this program to Groovy, Kotlin, or a different JVM language on the longer run.
Using Windows 10 because getting old java is a pain on Linux, after installing both JRE and JDK 8, and Gradle 6.0.1 (latest) and Gradle 5.4 (was released around the time of the master push) I get the following error.
An exception occurred applying plugin request [id: 'org.golo-lang.golo', version: '0.6']
Failed to apply plugin [id 'org.golo-lang.golo'] >

Since the Golo compiler Gradle plugin does not seem to compatible with the newest Gradle versions, add the Gradle wrapper to this project, so that the user is not required to install a specific (outdated) Gradle version to compile this project.
While the program can run smoothly for months, from time to time the program seems to hang.
Some early investigation points to the SSDP handler as the cause. It has a clunky way to determine whether it should run or stay paused and it probably fails to detect that it needs to run from time to time. In certain situation it is never checked again whether its threads will need to run, so it can remain idle and never detect new devices on the network.
My current idea is to get rid of the Workers on the SSDP handler and just let the threads always run periodically. Since it knows which devices it has to detect, it can choose to do nothing each time it runs.
Thanks for building this cool piece of software! Looking forward to start scrobbling, but ran into following error message when running audiostreamscrobbler (configured with lastfm):

On my Raspberry pi 1 (Model B) AudiostreamerScrobbler is detecting MusicCast players on the network. It sends HTTP requests, but fails to receive UDP responses.
On my Windows development machine, this seems to be working fine.
Probably because of an obscure bug in the Golo compiler, this program cannot be compiled with the latest production release of Golo 3.3.
I have not been able to reproduce the error in a small script that can be given to the Golo developers yet.
