That sounds nice, but it also sounds flawed. One doesn't necessarily lead to the
other. Just because it was there doesn't mean they spent significant amount of
time optimizing it (as if like they could beat machine code optimizations
anyway).

I also question whether or not java had its beginnings before C/C++ compilers
started to support 64-bit types. The issue is not whether 64-bit types were a
part of the standard specifying the language. Java has been around since 1995 or
so, and you mean to tell me that since the 1960's when C was created, no one
ever found it necessary to add a 64-bit type to a C compiler? I find that one a
little hard to swallow.

In any case, I think you're making quite a stretch to over sell java.
