In Apache httpclient 4.*, why all the methods are deprecated? If all are deprecated , how can we use this class effectively.
When I do a PoolingClientConnectionManager.getTotalStats()
I see the following output
[leased: 2; pending: 0; available: 0; max: 20], and I never see available being above 0 at any concurrency.
Please advise.

The class PoolingClientConnectionManager itself is deprecated, so all methods are deprecated. Don't use the class. Instead, use PoolingHttpClientConnectionManager.
