Simply having == call equals() and a DIFFERENT method for
object identity would save a ton of bugs.

Is this mistake really made often by programmers beyond the
beginner stage with Java? If it is, maybe you have a point,
but if it's made mostly be people new to Java, it seems to
me that there are some downsides:

It would further obscure the fact that all non-primitive variables
are references, not objects.

It also would introduce one more way in which references and
primitives are different. As it is now, "x == y" evaluates to
true if variables x and y are equal, and this is true no matter
whether x and y are primitives or references.

And it seems to me that unless you made a similar change to
the assignment operator (so that "x = y" copies the object
contents if x and y are references), again you'd have something
that feels inconsistent. (I haven't thought this part through
very carefully, though.)
