Carl, this is why I have said from the beginning that some registration
process is required. Obviously, we cannot know.
Even though it is quite rare to use slashes in the arguments
for Windows Native Applications (WNA), we cannot generalize that
every argument that contains slash means directory.
For example, Oracle's SQL Plus will accept the argument like
"user/passwd AT instance" - but then who will use this in Windows ?
Everyone I know (includeing myself) clicks on the icon to launch this.

Anyway, one possible way would be like:

% regwna javac       # register javac as wna and convert all arguments
                               #     that contains slashes into MS dos path 
names

% regwna javac -1   # Same as the above but only the first argument
% regwna javac -$   #  only the last argument
% regwna javac -aname "-classpath"   # only the argument for -classpath
% regwna javac - r   #  remove javac as wna.
                               #  etc etc ... I think that the developers 
have a better
                               #    idea of how this may be designed.

I don't think that this will completely solve the problem mathematically,
but I am quite certain that 99.9% of the problems related with path
incomatibility problem will be resolved.

Thanks,
