| * 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. |
