Change in `url.openStream` behaviour in later Java 8 versions

Question

I have a program that opens a file from our internal SVN by using

url.openStream();

on that url. This works fine with Java 7 and also with jdk1.8.0_161.

But, when I tried with the OpenJDK version jdk8u202-b08, I get

java.io.IOException: Server returned HTTP response code: 401 for URL: ...

Has the behaviour of openStream changed in later build versions of Java 8? If so, how can I solve this problem?

EDIT:

Additional tests showed that OpenJDK in version 8u192 works as well. So it must be a change between build version 192 and 202.

Can you try also with the latest release (u212-b04) https://adoptopenjdk.net/archive.html ? If it is a regression, maybe it has been fixed already. — Thilo, Jul 15 '19 at 11:30

My colleague finally found out that there is a change in the default behaviour of the authentication. You can reverse this by using

java -Djdk.http.ntlm.transparentAuth=enabled -Djdk.http.ntlm.transparentAuth=trustedHosts
