    Default Java Exception when installing on a Mac

    I'm getting:
    Tom:/Users/tug root# /opt/zimbra/libexec/
    Exception in thread "main" java.lang.UnsupportedClassVersionError: com/zimbra/cs/localconfig/Main (Unsupported major.minor version 49.0)

    I have JDK 1.4 installed
    Tom:~ tug$ java -version
    java version "1.4.2_09"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)
    Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)

    Do I need to upgrade to 1.5?

    Default java

    Yes, upgrade, and search the forums for how to make 1.5 the default version (change symlinks in /System/Library/Frameworks...)

    Default Mac needs JDK 1.5


    It might be a good idea to add the requirement for 1.5 to the Installation Prerequistites section of the quick install guide.
