Go back and look at my response to the message you quoted :-)
The short answer is yes, it will work on Intel.

Pretty much, but it's never that simple (and wasn't for 32 bit mode either)

Now that they have both been out a while, compilers generally produce
code that work on both. Tricky things like JVMs and esp kernels needed
explicit support.

Support is a different issue.  It may work, but it may or may not be a
"supported" platform of the JVM vendor.
