Is TikaExceptionMapper in tika-server actually used?

[Allison, Timothy B.]

All,

  In working on adding the stacktrace from a parse exception to the server 
response, I'm trying to find the most jax-rsly elegant way of handling 
exceptions.  There seems to be a bit of duplicated code, some with good reason, 
for exception handling.  Is TikaExceptionMapper actually used by anything?  If 
not, should I try to modify code to use it or something similar to it?

   Thank you.

           Best,

                Tim
