You're running out of RAM. You're going to need to get 64 bit java which requires a 64 bit operating system (OS). If you don't know if your OS is 64 or 32 bit, you can check it by going to control panel>System and Security>System. If you have a 64 bit OS then you can proceed to get 64 bit java by going here and downloading the file named: jre-8u101-windows-x64.exe or the 102 version, it doesn't really matter. After it has downloaded, run it and install it. Next go to the Technic Launcher and click on launcher options in the upper right corner. Click on the Java Settings tab and make sure the java version is the one you just installed. Then directly below that change your Memory to 2G or more. That's it, launch the modpack, go through the portal, and it should work.
