/**
|
|
* Is a reference to Connections that is stored in Pool.
|
|
* This is an intermediate object that is outside of the circular
|
|
* reference loop of
|
|
* com.sun.jndi.ldap.Connection <-> com.sun.jndi.ldap.LdapClient
|
|
* <-> com.sun.jndi.ldap.pool.Connections
|
|
*
|
|
* Because Connection is a daemon thread, it will keep LdapClient
|
|
* alive until LdapClient closes Connection. This will in turn
|
|
* keep Connections alive. So even when Connections is removed
|
|
* from (the WeakHashMap of) Pool, it won't be finalized.
|
|
* ConnectionsRef acts as Connections's finalizer.
|
|
*
|
|
* Without connection pooling, com.sun.jndi.ldap.LdapCtx's finalize()
|
|
* closes LdapClient, which in turn closes Connection.
|
|
* With connection pooling, ConnectionsRef's finalize() calls
|
|
* Connections.close(), which in turn will close all idle connections
|
|
* and mark Connections such that in-use connections will be closed
|
|
* when they are returned to the pool.
