Subject [jira] Commented: (JCS-32) Shutdown hook does not actually save keys to disk

Aaron Smuts commented on JCS-32:
--------------------------------

I'm going to move the shutdown hook to the composite cache manager.

> IndexedDiskCache add a Runtime's shutdown hook to dispose itself. However, this behaves
differently from calling CompositeCacheManager.shutdown(). The former fails to save the keys
into the disk while the latter can do so. Below is the run log from IndexedDiskCache.Shutdown
running during JVM shutdown: (index and data file is empty)
