Closed xXSchrandXx closed 5 years ago

xXSchrandXx commented 5 years ago

Platform Information

$ java -jar SubServers.Host.jar -v

Linux 3.16.0-4-amd64 [x64],
Java 1.8.0_191 [x64],
GalaxiEngine v3.2.0c (19w22a),
SubServers.Host v2.14a (19w22a)

What Happened

Starting SubServer.Host.jar with a chrooted User:

$ java -jar SubServers.Host.jar
Exception in thread "main" java.lang.NullPointerException
        at net.ME1312.SubServers.Host.ExHost.<init>(ExHost.java:231)
        at net.ME1312.SubServers.Host.ExHost.main(ExHost.java:126)
        at net.ME1312.SubServers.Host.Launch.main(Launch.java:28)

Additional Information

Chrooted User does can use java (Paperspigot does start normal)

It seems that this is a rare instance where something went wrong before the engine was started. Unfortunately, SubServers.Host was not equipped to handle such problems and so the error handler is actually the one that threw that error. 🤔

Anyway, since this issue does not show up in my tests, I'm going to have to ask you to re-run the app with 19w22b to get to the root cause of of the issue.

Now:

$ java -jar SubServers.Host.jar -version

Linux 3.16.0-4-amd64 [x64],
Java 1.8.0_191 [x64],
GalaxiEngine v3.2.0c (19w22b),
SubServers.Host v2.14a (19w22b)

Error:
