Hello!
I have recently came across an that prevents any instance from launching when using Java 1.9.0. I have tested, and found out it's not a minecraft-sided problem,because the game launched without any problems using the official launcher.
I have java 9 Build 118
I am running "MultiMC 5 - Version 0.4.12-develot-785 on win32"
I am using _Windows 10 Pro ; version 1511 ; OS build 10586.318 ; x64_
I have an _AMD A10-7800_ CPU; _AMD R7 240_ 2GB GPU; _8 GB DDR3 700Mhz_ RAM
Log from console: http://pastebin.com/EDimPgGx
I tried all versions from 1.6.4 up to 1.9.4, all give the same crashlog.
I hope you can fix this!
Can confirm, this doesn't happen under Linux but it definitely does under Windows 10 32 bit.
Can also confirm that it doesn't happen with the vanilla launcher.
edit.
I have to correct myself, it does happen under Linux with the newest oracle java 9 JRE.
This is likely not going to be fixed with the current launcher part.

Expand all the bullet points.
This also involves changes to user configuration and java detection - we won't be using the executables anymore.
Java 9 officially released today, and I ran into this (tried both the "stable" and "development" update channels). I guess I'll switch MultiMC back to Java 8 for now, but I'll keep an eye on this issue in case this gets fixed.
Java 9 is not going to be supported any time soon. It breaks too many things.
Current version (0.6) should have no issues with Java 9 anymore. You will still find out that it doesn't work with mods... so it's sort of useless IMO. Closing.
