org.jasig.portal.concurrency.LockingException
A LockingException describes a problem that has arisen during an attempt to create or alter an IEntityLock. If the problem occurs in the lock store, the LockingException should wrap an Exception specific to the store, like a java.sql.SQLException. @author Dan Ellentuck @version $Revision: 19776 $
org.jboss.cache.lock.LockingException
Used for all locking-related exceptions, e.g. when a lock could not be acquired within the timeout, or when a deadlock was detected or an upgrade failed. @author Bela Ban.
