[jetty-dev] jetty client socket fd leak issue

[Junwei Sun <sun_junwei@xxxxxxxxx>]

Hi All,

I'm using jetty client(jetty-client-7.4.5.v20110725)as http client to download html pages, but find that jetty client has socket fd leak issue.
When jetty client download a URL which domain can not be resolved, it will leak a socket fd, such as URL "http://com.br/".
It will throw an UnresolvedAddressException:

Then, a socket fd leaked, just like the following fd:

$ lsof -p 4499|grep sock
java    4499 sunjw   41r  sock        0,6      0t0  151513 can't identify protocol
java    4499 sunjw   42r  unix 0xf4ffc700      0t0  151855 socket
java    4499 sunjw   43r  sock        0,6      0t0  151515 can't identify protocol

Is there any method of http client to close these socket(s)?
Thanks.
