如何将LdapConnectionPool与VirtualListViewControl结合使用？

我先梳理下目前遇到的情况和观察到的关键点：

• 使用VirtualListViewControl时，必须复用同一个LdapConnection才能保证功能正常。
• 使用LdapConnectionPool的话，没办法指定获取某一个特定的连接。

我研究了LdapConnectionPool的实现逻辑，发现连接池会把连接交付给客户端，客户端完成操作后必须调用：

connectionPool.releaseConnection(con)

在调用这个方法之前，该连接不会被归还到池中供其他客户端使用。

而对于VirtualListViewControl，我需要维护一个cookieid到LdapConnection的映射关系。用户可能会长时间滚动列表，要是一直占用着连接，感觉有点浪费资源；但如果在第一次请求后就释放连接，那后续用户滚动的时候，这个LDAPConnection可能会被其他线程同时使用。

不过从Java文档来看，这种并发使用的方式是安全的：

/**
...

• This class is mostly threadsafe. It is possible to process multiple
• concurrent operations over the same connection as long as the methods being
• invoked will not change the state of the connection in a way that might
• impact other operations in progress in unexpected ways. In particular, the
• following should not be attempted while any other operations may be in
• progress on this connection:

• return (<UL>
  )
  

• return (<LI>
  )
  

• Using one of the {@code connect} methods to re-establish the connection.
  

• return (<LI>
  )
  

• Using one of the {@code close} methods to terminate the connection.
  

• return (<LI>
  )
  

• Using one of the {@code bind} methods to attempt to authenticate the
  

• connection (unless you are certain that the bind will not impact the
  

• identity of the associated connection, for example by including the
  

• retain identity request control in the bind request if using the
  

• LDAP SDK in conjunction with a Ping Identity, UnboundID, or
  

• Nokia/Alcatel-Lucent 8661 Directory Server).
  

• return (<LI>
  )
  

• Attempting to make a change to the way that the underlying communication
  

• is processed (e.g., by using the StartTLS extended operation to convert
  

• an insecure connection into a secure one).
  

**/
@ThreadSafety(level=ThreadSafetyLevel.MOSTLY_THREADSAFE)
public final class LDAPConnection
implements FullLDAPInterface, LDAPConnectionInfo, ReferralConnector,
Closeable
{

但奇怪的是，LdapConnectionPool非要等到连接被释放才会把它重新分配出去。所以我想请教下，把LdapConnectionPool和VirtualListViewControl结合使用的话，最优的方式是什么？
