If Sun wanted to cover themselves legally they could have simply stated
that you use the language and compiler at your own risk and that they
cannot guarantee that the produced code is correct or acting as
intended. The point that they especially writes that one should use it
for situation X and Y means to me that they do think their product IS
NOT suitable to be use in situation X and Y.
My point is simply:
1. They don't want people to use the compiler/language for X and Y
2. They don't want lawsuits due to bugs in compiler/language generally

The analogy doesn't hold in my opinion. The warning would have to be
"Don't use this equipment to do X and Y" to be analogous with the above
:-)
