167  * A simple memorizing {@link Supplier} of {@link RepositorySystem} instance, that on first call
168  * supplies lazily constructed instance, and on each subsequent call same instance. Hence, this instance should be
169  * thrown away immediately once repository system was created and there is no need for more instances. If new
170  * repository system instance needed, new instance of this class must be created. For proper shut down of returned
171  * repository system instance(s) use {@link RepositorySystem#shutdown()} method on supplied instance(s).
172  * <p>
173  * Since Resolver 2.0 this class offers access to various components via public getters, and allows even partial object
174  * graph construction.
175  * <p>
176  * Extend this class {@code createXXX()} methods and override to customize, if needed. The contract of this class makes
177  * sure that these (potentially overridden) methods are invoked only once, and instance created by those methods are
178  * memorized and kept as long as supplier instance is kept open.
179  * <p>
180  * This class is not thread safe and must be used from one thread only, while the constructed {@link RepositorySystem}
181  * is thread safe.
182  * <p>
183  * Important: Given the instance of supplier memorizes the supplier {@link RepositorySystem} instance it supplies,
184  * their lifecycle is shared as well: once supplied repository system is shut-down, this instance becomes closed as
185  * well. Any subsequent {@code getXXX} method invocation attempt will fail with {@link IllegalStateException}.
