Hello, I hope this is the right place to report potential bugs.
When updating to version 5.4 our Java 8 tests fail with the following exception:
java.lang.UnsupportedOperationException: method is not supported because of the
TLS half-close policy

It seems to be a bug, but please let me know if it is a mistake on our side.
I have put together the following test class, which fails in Java 8 with the
above exception, but finishes correctly with Java 11
(tested on Windows 10, but the Java 8 exception also occurs on Linux in our
integration):
import org.apache.hc.client5.http.classic.methods.HttpGet;
import org.apache.hc.client5.http.impl.classic.CloseableHttpClient;
import org.apache.hc.client5.http.impl.classic.HttpClientBuilder;
public class J8HttpsErrorTest {
public static void main(String[] args) {
System.out.println(System.getProperty("java.vm.vendor")
+ " " + System.getProperty("java.vm.name")
+ " " + System.getProperty("java.vm.version"));
try {
CloseableHttpClient client = HttpClientBuilder.create().build();
String responseStr = client.execute(new
HttpGet(https://www.google.com/), response -> {
byte[] content = new byte[1024];
int length = response.getEntity().getContent().read(content);
// just read the first view bytes to show the connection works
String str = new String(content, 0, length);
response.close();
return str;
});
System.out.println("Sucessfully loaded: " +
responseStr.replaceAll(file://s, " "));
System.out.println(">>>");
client.close(); // this causes the
ExceUnsupportedOperationExceptionption in Java 8
System.out.println("<<<"); // <== success expected, except for Java
8
} catch (UnsupportedOperationException e) {
System.out.println("!!!");
e.printStackTrace(System.out); // <== exception expected for Java 8
} catch (Throwable e) {
System.out.println("!!!!!");
e.printStackTrace(System.out); // unexpected!
}
}
}
