A JNDI lookup does not have to be slow. The JNDI context implementation can
certainly be optimized to provide fast lookups for local home objects.
In the case of Ejipt, a lookup call on a local JNDI context (for local home
objects) is only a method call slower than the Ejipt specific convenience
method that essentially does a hash map lookup.
