Shouldn't JavaScript be reading the JSON and comparing what it thinks are the contents of the JSON with the binary coming from Java and C++? Here it looks like it is reading the C++ and Java binary files and comparing them. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
