怀疑提供的api没设置timeout导致线程一直被hold住

[Stevenhuangqian]

最近接入了信鸽推送发现通道莫名会无法发送。工程内所有功能正常，内存、cpu、io都没问题 查看了下堆栈，发现开的所有线程都是卡住： java.lang.Thread.State: RUNNABLE at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.socketRead(SocketInputStream.java:116) at java.net.SocketInputStream.read(SocketInputStream.java:171) at java.net.SocketInputStream.read(SocketInputStream.java:141) at sun.security.ssl.InputRecord.readFully(InputRecord.java:465) at sun.security.ssl.InputRecord.read(InputRecord.java:503) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973) - locked <0x00000004ed23d1a0> (a java.lang.Object) at sun.security.ssl.SSLSocketImpl.readDataRecord(SSLSocketImpl.java:930) at sun.security.ssl.AppInputStream.read(AppInputStream.java:105) - locked <0x00000004ed23d1b0> (a sun.security.ssl.AppInputStream) at java.io.BufferedInputStream.fill(BufferedInputStream.java:246) at java.io.BufferedInputStream.read1(BufferedInputStream.java:286) at java.io.BufferedInputStream.read(BufferedInputStream.java:345) - locked <0x00000004ed2832c8> (a java.io.BufferedInputStream) at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:704) at sun.net.www.http.HttpClient.parseHTTP(HttpClient.java:647) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1569) - locked <0x00000004ed287338> (a sun.net.www.protocol.https.DelegateHttpsURLConnection) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1474) - locked <0x00000004ed287338> (a sun.net.www.protocol.https.DelegateHttpsURLConnection) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254) - locked <0x00000004ed2872e0> (a sun.net.www.protocol.https.HttpsURLConnectionImpl) at com.tencent.xinge.XingeApp.callRestful(XingeApp.java:109) at com.tencent.xinge.XingeApp.pushApp(XingeApp.java:60)

看了下源代码。感觉是没设置超时时间，并且信鸽服务器也没主动断开。线程一直hold住？
