Not sure what is misleading here. The lock token is the result of
creating a lock. The username used for creating a lock is taken from
cached credentials. Cached credentials are independent of working
copy and not stored in the working copy. Only the resulting lock token
and the lock owner (username who created the lock) is stored in the
working copy. The lock owner username is not used for general SVN
authentication, only for authorization of operations relating to that
specific lock.

Ah, NetBeans sets it to ${netbeans-userdir}/config/svn/config/auth it seems.
In any case, it's not saved per-working copy.

The kind of repository should not be relevant for this.

That seems correct to me, since the lock was created by user2 and you
are trying to unlock it as user1.

It's the same file, but in a different working copy (Project1 vs
Project2). Locks are working-copy specific (by means of the lock token
stored in the working copy). Test cases #3 and #4 are testing that you
can "steal" a lock owned by one working copy to another working copy
using the "force" option.

Test case #5 says "select some Java file" in step 1. It is implicit
that this should be a file that isn't locked yet, although I agree it
would be better if the test case made this explicit. Test case #5 is
testing that the lock is actually doing its job, namely preventing
commits from another working copy to the locked file.
