Need help with BrewEvent

As you might have noticed, BrewEvent returns items in Brewing stand before they are actually merged. This is very inconvenient, so I'm asking, does anyone have a freely available class or piece of code, that returns brewing result from ingredients ?

If you agree that Brewing api should be improved, please support this issue by voting for it and commenting it to bump it.

I created this little class to help myself a bit - https://gist.github.com/raGan262/5380923
I got data values and other information from minecraft wiki. I'm not completely sure when exactly are reverted potions created, so I guess I'll have to try out to see. Be sure to let me know if it's wrong or you have better solution to this.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Bump for better brewing.
