在我的單元測試，我使用Commons的HttpClient請求不正確遠程Web站點，最大超時爲：如何在查找主機時設置套接字超時？
@Test(timeout = 10000)
public void should_not_be_accessible_if_configuration_is_incorrect() throws Exception {
// use httpclient to visit an invalid remote http web site
}
但它可能在某些計算機拋出這樣的例外：
java.lang.Exception: test timed out after 10000 milliseconds

似乎它阻止的方法：java.net.Inet4AddressImpl.lookupAllHostAddr()
我不知道是否有任何方法來設置它的最大超時？

@ sasanad號這些連接和讀取超時。這個問題是關於DNS超時的。與此問題相關的唯一答案是[我]（http://stackoverflow.com/a/15519363/207421），它不提供此OP的解決方案。 – EJP
