First off, anyone using 32-bit Java probably shouldn't even consider running modded Minecraft... 32-bit CANNOT access the amount of ram needed by mod-packs of any size, about 4GB. 32-bit Windows can only access 3GB, and a minimum of 1GB of that must be reserved for the OS, even more if you have integrated graphics.

Oracle Java is the normal "official" Java... If you load vanilla directly from Mojang with their new launcher (or Modded from Curse, since it uses the Mojang launcher) the Mojang launcher will automatically load a runtime of Java 1.0.8_25 as the officially supported version, so if you use either of those you don't need to worry about Java at all as Mojang will change the loader as the preferred version changes.

I've just loaded 1.0.8_65 on my newly formatted and loaded Windows 10 system and have seen no problems at all.

Even Vanilla Minecraft struggles if you run on 32-bit Java (it runs into memory issues on Far render distance). Modded Minecraft won't work at all. Make sure you have a 64-bit OS and a 64-bit version of Java.

If your CPU does not support 64 bits, then it's too old to run any modpack at any reasonable level of performance anyways.

Agreed. If you can't use 64 bit Java, you either have an ancient Pentium 4(or older), or an older Intel Atom(newest ones support 64 bit.) Neither of which are capable of handling FTB.

Or he has a 32 bit Operating System.

This can be the case... 64-bit CPUs are fully able to run the 32-bit versions of OSes, but the memory limitations still exist because of the 32-bit CPU's internal architecture.
