The terms have definitions. "Backward compatible" means that the new product
or framework will work with artifacts generated or created for an earlier version.
"Forward compatible" means that an artifact from an earlier version works in 
a later version of the product or framework.

The terms are only confusing if you don't know the meanings. That is true 
for all terminology, of course.

Yes, it does, provided you use the "-source", "-target" and "-bootclasspath" 
options.

Why would you spread misinformation about that?
