Well, the fact that they typically are is evidence that they do, is it

Whether one likes it or not is not actually relevant. There are
objective reasons to turn assertions on or off, a decision made by the
operations staff as pointed out upthread. Assertions can be enabled
or disabled at a pretty fine-grained level; it's not just all-or-
nothing for the application.

The question isn't whether one "likes to turn assertions on", but when
it's useful to do so.

That depends in part on whether the programmer was smart enough to use
assertions for the correct purpose, and not as some sort of substitute
for exceptions.

There really is plenty of material on Sun's site and elsewhere as to
how to use assertions correctly. There is no excuse to use them
