/**
* Provides the PasswordAliasStore behavior using a JCEKS keystore.
*
* The keystore is actually managed by the PasswordAdapter, to which
* this implementation currently delegates its work.
*
* Note that this service is currently per-lookup. This is so that each
* use of the alias store gets the current on-disk information. Ideally we can change this
* when we can use Java 7 features, including the WatchService feature.
*
* This class's methods are not
* synchronized because the PasswordAdapter's methods are. If this implementation
* changes so that it no longer delegates to those synchronized PasswordAdapter
* methods, then make sure that the implementation is thread-safe.
*
* Note that the domain-scoped password alias store service class extends this
* class. As a service, that class will be instantiated using the no-args
* constructor. So the actual initialization of the class occurs in the init
* method. The domain-scoped service class invokes the init method itself.
* Any code that needs to create some other alias store can use the newInstance
* method to provide the location of the alias store file and the password.
