If it is a problem, it is in JavaHL not Subclipse. It is up to the
adapter to report errors.

FWIW, I thought that in the situation you describe, you typically do not
get an error, which is actually bad. The copy command will just copy
inside of the target instead of creating the target. There was a big
discussion about this on the SVN users@ list just a few weeks ago.

Consider the scenario where a company uses an incrementing tag name
policy. If two users try to use copy to create the same tag name. For
example, they both run this command:

svn cp url://repos/Project/trunk url://repos/Project/tags/tag50

The first user will get:

/tags
  |--tag50

And the second user will get:

/tags
  |--tag50
     |--trunk

I just verified this using the command line. Only the 3rd time that you
run the command will it fail, because now it wants to create "trunk" but
it already exists.
