---------------------------------------
Summary: The CloseableHttpClient is shut down due to an
java.lang.StackOverflowError exception
Key: HTTPCLIENT-2256
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2256
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.13
Reporter: liqiang.liu
Attachments: image-2023-01-11-20-25-17-784.png
builded the CloseableHttpClient via the code
~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();~
~}~
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
