the class CacheManagerImpl method close.

/**
 * The shutdown takes place in two phases. First all caches are notified to
 * cancel their scheduled timer jobs, after that the shutdown is done. Cancelling
 * the timer jobs first is needed, because there may be cache stacking and
 * a timer job of one cache may call an already closed cache.
 *
 * <p>Rationale exception handling: Exceptions on shutdown just could silently
 * ignored, because a shutdown is done any way. Exceptions could be happened
 * long before in a parallel task, shutdown is the last point where this could
 * be propagated to the application. Silently ignoring is bad anyway, because
 * this will cause that serious problems keep undetected. The exception and
 * error handling within the cache tries everything that exceptions will be
 * routed through as early and directly as possible.
