I click "Launch client" and it just closes. 

Try the following:

Uninstall JAVA/JDK Completely: 

Uninstalling the JDK

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:^Foot1

/Library/Java/JavaVirtualMachines/jdkmajor.minor.macro[_update].jdk

For example, to uninstall 8u6:

% rm -rf jdk1.8.0_06.jdk

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.

Install this version of JDK 8:

ALSO MAKE SURE JRE IS INSTALLED! 

Note: JRE is auto installed with JDK Installer

 

Then load DreamBot:

java -jar DBLauncher.jar
