See the release notes for BFG v1.12.4 :
https://github.com/rtyley/bfg-repo-cleaner/releases/tag/v1.12.4

You say you have Java 8 installed, which _should_ work fine - but the error
you report makes it look like you are actually running the BFG with Java 6.

On Mac OS X you can get this problem:

Hope this helps - let me know how it goes!

I just downloaded Java 8 for OS X (I'm running 10.10.5 as well) and BFG v1.12.8 and saw the exact same error. Using v1.12.3 worked.

See this StackOverflow answer if you've installed Java 7 or above on Mac OS X but the Terminal is still using Java 6:

Thanks! The answer explaining that the Java installer doesn't overwrite Apple's version (http://stackoverflow.com/a/14875241/2635396) fixed the issue for me.

I Installed Java 8 but still had the issue. This answer helped me sort out the version of Java on Mac osx in the terminal. http://stackoverflow.com/a/14875241/2734319
