Java 8 Required as of PhantomBot 2.3.3

  • Bot Developer

    If PhantomBot 2.3.3 or later is started up and appears to hang, please review the stacktrace.txt file. You may see a message such as:

    11-04-2016 @ 19:09:25Z (Thread[main,5,main]) java.lang.UnsupportedClassVersionError: net/dv8tion/jda/exceptions/RateLimitedException : Unsupported major.minor version 52.0

    The library that is used to provide Discord support requires Java 8, and as such, you will need to ensure that you have Java 8 installed on your system.

    [EDIT] Upcoming launch scripts will detect what version of Java is being used and not start PhantomBot.

    Please install Java 8 onto your system to resolve the issue.
