Update:  I just tried version 10.13.1.1217 and it loads just fine.  Can someone help me with the current recommended release though?

switched to pack 7..... issue persists... now what?

Make sure you uninstall ALL java 1.8 versions, then REinstall your java 1.7.. I had lingering binaries somehow and needed to reinstall 1.7 to clear the bad binaries..

Again, nothing wrong with Java 8. You just need to use latest Forge.

 

You might want to explain that it was just fixed, 2 days ago.. and the version that's needed instead of saying "latest" since that's not "recommended" and people may think you mean the -doesn't work with 1.8_20- version, instead of the newly fixed version.

 

So.. if you're running Java 1.8_20, you need Forge version 10.13.1.1217 which was just fixed for 1.8_20 on the 14th.

Just use build numbers they are there for a reason -.-

Build 1210+ is far less ambiguous.
