liqiang.liu updated HTTPCLIENT-2256:
------------------------------------
Description:
builded the CloseableHttpClient via the code
{code:java}
private static final CloseableHttpClient HttpClient = bulidClient();
private static CloseableHttpClient bulidClient() {
HttpClientBuilder httpClientBuilder =
HttpClients.custom().setMaxConnTotal(1000).setMaxConnPerRoute(1000);
httpClientBuilder.setDefaultRequestConfig(RequestConfig.custom().setConnectionRequestTimeout(2000).setConnectTimeout(3000).setSocketTimeout(4000).build());
httpClientBuilder.setDefaultSocketConfig(SocketConfig.custom().setSoLinger(0).setSoKeepAlive(false).setTcpNoDelay(true).setSoTimeout(4000).build());
httpClientBuilder.setDefaultConnectionConfig(ConnectionConfig.custom().setBufferSize(8192).build());
httpClientBuilder.setRetryHandler(new DefaultHttpRequestRetryHandler(2, false));
return httpClientBuilder.setConnectionManagerShared(true).build();
} {code}
The HttpClient becomes unavailable when a java.lang.StackOverflowError
occurs. Even if the jvm recovers. I found out why:
class MainClientExec in the source code closes the connection pool when an
StackOverflowError occurs, causing the client to fail to recover.

I expect it to keep working when something goes wrong
