Examples of net.sf.ehcache.CacheException

net.sf.ehcache.CacheException
A runtime Cache Exception.
These exceptions may be handled by a CacheExceptionHandler registered with a Cache. The handler provides a key if it is available. A convention that should be followed in exception messages is to include in the message "key keyValue" e.g. "key 1234" so that keys can be parsed out of exception messages.
Updated in version 1.5 to remove getInitialCause which was a left over from the pre-JDK1.4 days. It breaks JAXB. @author Greg Luck @version $Id: CacheException.java 744 2008-08-16 20:10:49Z gregluck $
