Hi I've been having a problem with the technic launcher on my iMac with 32 bit java. Everytime I try to open the technic launcher I get a message that says "The Java JAR file "technic-launcher-latest-5.jar" could not be launched." When I check the console this is what comes up:

Does anyone know how to fix this?

Sorry I also forgot to add that my computer does not support 64 bit java. I don't know if that causes any problems but I just wanted to add that.
