NPE at it.gotoandplay.util.launcher

Hi, we are experiencing this kind of exception when creating a room on server side:

Code: Select all

java.lang.NullPointerException
        at it.gotoandplay.util.launcher.JarFilesUtil.scanFolderForJarFiles(JarFilesUtil.java:23)
        at it.gotoandplay.util.launcher.JarLoader.loadClasses(JarLoader.java:19)

        at com.smartfoxserver.v2.entities.SFSZone.createRoom(SFSZone.java:266)

Since the exceptions appeared in the log, no room can be created (it always crashes on this exception).
We are using SFS 2.13.4

Hi,
something is wrong with the jar file(s) you have deployed or the Extension configuration.
It looks as if you are passing a path that doesn't exists, for your Room Extension.

Hope it helps

It cannot be, because there have been hundreds of rooms created prior that error without server restart nor any change to the jar file

Have you tried restarting the server and see if the problem goes away?
Thanks
