Industrial Foregoing Version: 1.12.11 (to be more precise, I am looking at d8170bd)
TeslaCoreLib Version: 1.12.2-1.0.15 (remark: this issue has nothing to do with TeslaCoreLib)
Crashlog (If Any): N/A

In com.buuz135.industrial.proxy.CommonProxy, we have this for retrieving a contributor list:

https://github.com/Buuz135/Industrial-Foregoing/blob/d8170bd9e307afd2ebfaa97ca692d0b98414e0ad/src/main/java/com/buuz135/industrial/proxy/CommonProxy.java#L195-L199

The readUrl call turns out to be a blocking I/O operation:

https://github.com/Buuz135/Industrial-Foregoing/blob/d8170bd9e307afd2ebfaa97ca692d0b98414e0ad/src/main/java/com/buuz135/industrial/proxy/CommonProxy.java#L92-L108

Under certain low-quality internet conditions, this call will cause the game initialization process to hang until timeout. The symptom looks just like the process enters a dead loop.
The preferred way to handle this is to retrieve this list on a separate thread, i.e. something like this:

new Thread(() -> {
  new JsonParser().parse(readUrl(CONTRIBUTORS_FILE))....;
}).start();

Can you fix this quicker? It has stuck my game start so many times, especially in Linux environment. @TheCodedOne

👋 Sorry but Industrial Foregoing has ended support for version 1.12. I'm closing this issue as it will no longer be updated for that version. Thanks for playing with the mod.
