Downgrading from "Java for OS X Lion Update 1"
I don't know where to find original version of Java for Mac OS Lion.

At least you can download Java Developer Package for Mac OS X 10.7 with your AppleID or try Java Developer Package for Mac OS X 10.7 Update 1 package to be sure if this bug is here.

Tutorials how to downgrade your Java you can find here and here.
