Subject [jira] Created: (JCS-32) Shutdown hook does not actually save keys to disk
Date Tue, 13 Nov 2007 04:24:51 GMT
Shutdown hook does not actually save keys to disk
-------------------------------------------------

                 Key: JCS-32
                 URL: https://issues.apache.org/jira/browse/JCS-32
             Project: JCS
          Issue Type: Bug
          Components: Indexed Disk Cache
    Affects Versions: jcs-1.3
            Reporter: Andy
            Assignee: Aaron Smuts
            Priority: Minor


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)
