Ive recently re-installed my OS after a hard disk crashed, and installed Java 8 as the preferred java install as, between the native launcher and various forum threads it seemed that java 8 had become the preferred version.

Since then however I can no longer launch any pre 1.7.10 pack as they all fail very early with a ConcurrentModificationException. Is this known or have I screwed up my Java 8 or modpack install in some interesting way?
 
it is indeed a known problem and there is only a fix for minecraft 1.6 by the name of forgefix or something like that.

The patch on that thread works.

Awesome!

Now to edit all my profiles to remove the maxPermSize option once and for all.

Just a note. This isn't really necessary. Java 8 will not fail to load with the maxpermsize option. It'll just ignore it.
