    Fresh install of 3.7.5. Using Java 1.8.0_181. OS: CentOS Linux 6.10.
    Create new campaign from DM license. Put in name, chose D&D 5.0, chose D&D SRD, put in password, chose direct IP networking and oversized layout. Clicked ok. Process to start campaign began and then error box appeared with "Unexpected throwable initializing app. java.lan.NullPointerException." Attaching D20PRO.log from server.

    AkosPrime, can you verify that the app is running against Oracle Java and not against OpenJDK?

    Have you tried creating a session without a campaign template, just to be certain this is happening in the root application and not in a subprocess.

    Thanks, I am definitely out sick at the moment, but will poke in to see if we cannot resolve this.

    I install Java from an Oracle tarball, here's the output of -version:

    [astocker@morgenes D20PRO-3.7.5]$ /usr/java/latest/jre/bin/java -version
    java version "1.8.0_181"
    Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
    Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)


    I'm afraid I don't know how to start a session without a campaign. I reinstalled from scratch, downloaded my license, launched a GM session, and it prompts me to load a campaign. I click on 'Cancel' to get out of that window but nothing happens (other than a non-window killing exception getting thrown, at least according to the scrolling printout from the d20Pro.sh window.)

    I've tried choosing different game systems and rules as well as selecting <NONE> as options for those and it doesn't make a difference, when I go to host the game, the program thinks for a bit and then throws the Error window with the java exception.

    Just to confirm I went back and blew away my 3.7.4 directory, redownloaded and unzipped that version, downloaded my license, activated the GM, set up a campaign, and launched it successfully with the host option. So at the moment my problem seems to be confined to 3.7.5 (although I had other issues with 3.7.4 of course.)


    If you want, I can update the Java to 1.8.0_191, but I've been avoiding it at the moment because we're having issues with that version at work and I didn't want to create any additional problems at home.

    Jumping on this thread - hope you do not mind.

    Updated from 3.7.4 to 3.7.5 a couple of weeks ago. One user using Windows, we are running a Pathfinder game, gets the error now under 3.7.5 (never had that issue with 3.7.4). I can get more user specs, or my log if needed (not sure if log still needed if is a user issue). He updated his Java after first week it giving the error, still getting the error. Not sure if these are related, but leave it in your trusty hands if you need to pull this out of this thread. Thanks -- Please advise.

    we'd need the log file from the client in order to have an idea of what is going on.

    Finally got the log. See attached. User also noted now getting a bug message (not sure where it came from or if impacting or not) - maybe his machine is not allowing him to run something in D20Pro....but attaching anyway.

    Hello @Golldan.

    Java apps get abused pretty heavily by aggressive virus scanners. I would advise the player to reinstall the application with the virus scanner temporarily disabled. What happens is, programs like comodo and avast, will remove or block jar bundles from the install.

    From the log, it looks like the core memory access for the application is being blocked.

    Additionally, the package appears to be blocking the core Chromium bundle which D20PRO uses to manage many of it's http communications.

    My advice would be to have the player follow the instructions here for temporarily disabling their scanner:

    http://help.comodo.com/topic-72-1-623-7648-.html

    then re-run the install and test.
