+/**
+ * This is the entry point of the validation engine.
+ * The maven build script packages the application as a 'all-in-one' jar. As such, there are 2 ways to start
+ * the application:
+ * java -jar ASC-Validator-some_version.jar
+ * or
+ * java -cp some_path/ASC-Validator-some_version.jar org.springframework.boot.loader.JarLauncher
+ *
+ * The second version is important because it gets around the known java issue/bug of not being able to specify
+ * additional classpath elements when using the '-jar' option (additional '-cp' options are being ignored). This
+ * version allows to add to the classpath the location of additional configuration.
+ *
+ * The approach in packaging the application was to include in the (all-in-one) package the known configurations
+ * (such that it is as easy as possible to install/setup/start the applications) while still having the possibility
+ * of re-specifying (some of) the configuration.
+ *
+ * All out beans are specified within 'checker.xml'; use spring profiles to distinguish between the
+ * configurations for each environment.
+ * <beans profile="dev"> .. </beans>
+ * <beans profile="ist"> .. </beans>
+ *
+ * The default configuration is for the development environment. In order to run a particular configuration we use the
+ * spring.profiles.active environment variable, as in:
+ * java -Dspring.profiles.active=ist -jar some_path/ASC-Validator-Service-some_version.jar
+ * or
+ * java -Dspring.profiles.active=ist -cp some_path/ASC-Validator-some_version.jar org.springframework.boot.loader.JarLauncher
+ *
+ * Note: we can have a 'common' profile to be always activated that includes those bean specifications least likely to
+ * change.
+ *
+ * Resource reference syntax:
+ * classpath*:validator.xml
+ * vs
+ * classpath:validator.xml
+ *
+ * In the first case we direct the bean loader to find *ALL* validator.xml files in the classpath and merge them
+ * (merge the parts for the active profile(s))
+ * In the second case we instruct the bean loader to locate the *FIRST* validator.xml file and process it. All others
+ * (validator.xml) files will be ignored.
+ *
+ * Overwriting pre-packaged bean configuration:
+ * The first version would theoretically allow us to specify beans configuration deltas (with respect to the
+ * pre-packaged version). In practice I did not manage to have this approach working reliably: it relies on a
+ * deterministic order of classpath processing and on overriding some of the spring framework defaults (in not so
+ * obvious ways, bean indexing for example).
+ * Currently we enable the second option, i.e. one has to provide a FULL alternative bean configuration. This
+ * alternative configuration can be specified as overwriting an existing profile or as an entirely new profile.
+ * (when using alternative profiles the resourcec reference syntax is irrelevant ..)
