My problem is that the HttpClient never makes its way to the target. The target is on the same network (so I need no proxy) and it is definitely up. And the timeout was set quite high (120 seconds), the server is able to respond in less than a second.
Using other applications or curl everything works fine.
This is my code, I tried two ways of setting the credentials, they are marked with comments. During my tests I enabled first one then the other:
HttpRequest request = HttpRequest.newBuilder()
.uri(new URI( "https://target:8443/foo/bar"))
.version(HttpClient.Version.HTTP_1_1)
// approach 1:
.header("Authorization", basicAuth("foo", "bar"))
.timeout(Duration.ofSeconds(120)).POST(HttpRequest.BodyPublishers.ofFile(tempFile.toPath())).build();
HttpResponse<String> response = HttpClient.newBuilder()
/* approach 2:
.authenticator(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
System.err.println("Was asked for a password");
return new PasswordAuthentication("foo", "bar".toCharArray());
}
})
*/
.followRedirects(HttpClient.Redirect.ALWAYS)
.build()
.send(request, HttpResponse.BodyHandlers.ofString());
In contrast this one works:
curl -u foo:bar -X POST -H "content-type: application/vnd.lucidworks-document" https://target:8443/foo/bar --data-binary @test.json -v
My Java code throws this error:

The enabled logs don't show much, but this line makes me think that perhaps the authentication doesn't work and because of this the connection gets "stuck" ?!?

I'm aware that there are version of Java that have the problem I describe but I tried this on current versions of AdoptOpenJDK Java 11 (11.0.11+9) and 15 (15.0.2+7) and still experience the same.
