0N/A/**
0N/A * Is a reference to Connections that is stored in Pool.
0N/A * This is an intermediate object that is outside of the circular
0N/A * reference loop of
0N/A * com.sun.jndi.ldap.Connection <-> com.sun.jndi.ldap.LdapClient
0N/A * <-> com.sun.jndi.ldap.pool.Connections
0N/A *
0N/A * Because Connection is a daemon thread, it will keep LdapClient
0N/A * alive until LdapClient closes Connection. This will in turn
0N/A * keep Connections alive. So even when Connections is removed
0N/A * from (the WeakHashMap of) Pool, it won't be finalized.
0N/A * ConnectionsRef acts as Connections's finalizer.
0N/A *
0N/A * Without connection pooling, com.sun.jndi.ldap.LdapCtx's finalize()
0N/A * closes LdapClient, which in turn closes Connection.
0N/A * With connection pooling, ConnectionsRef's finalize() calls
0N/A * Connections.close(), which in turn will close all idle connections
0N/A * and mark Connections such that in-use connections will be closed
0N/A * when they are returned to the pool.
