> My mentor Rishi Verma noted on OODT-649 that several components used by the new CAS-Product
JAX-RS service, such as the file manager client and working directory, are being initialized
in the resource classes for every HTTP request.  This is inefficient and causes unnecessary
overheads, since these parameters (e.g. file manager URL and working directory location) are
assumed to be constant while the web application is running (i.e. if they do change, the web
application can be restarted to pick up the changes) and separate file manager client instances
aren't required for each request.
> Instead it would be better to initialize certain parameters only once when the web application
is started up and share them between the resource classes.
> Rishi also suggested that additional validation and logging would make the application
more robust and would help developers and users when configuring the web application.
