33 * Make this a java-scoped singleton to resolve the contextual issue spanning a Spring Context and
34 * accessing the SPR in other parts of the code that are not directly instantiated by a Spring Bean.
35 * Eventually the SPR doesn’t have to be a real singleton, it could simply be a Spring bean scoped
36 * as a singleton and then wired in via dependency injection to the classes that need it. But I’m
37 * not there yet. This will get a demonstrable extension mechanism in place quickly at practically
38 * no cost, beyond what’s already in the email plus some testing.
