When ever I click launch on any pack it does launch it ends with this Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0 can you help me out.

Clear out the Java command line flags in your client as they aren't needed anymore, or just ignore the error.. The Java 1.8 default is the equivalent of "PermSize=256m" and the new defaults for Minimum and Maximum ram are 2GB and 4GB, respectively... Looks like Oracle is aware of their "Garbage Collection" issue.

Then it's probably something else causing that which has nothing to do with this warning. Can you upload the launcher log?

What's causing the issue is probably that ClassNotFoundException, rather than the Java information.

Yup. I have seen this error before but I'm not sure what's causing it.
Maybe try redownloading the pack.

Weird that it affected all packs. Hopefully this won't happen again ^^

Are you using any packs older than 1.7? I've heard there may be issues with older packs and Java 1.8 due unsupported/older functions in previous java versions.

From what I've seen Java 1.8 is good for MC 1.7 based packs while Java 1.7 seems to be favored for MC 1.6 based packs and older.
