We cannot use this fix as we are not on Java 12. If you are, you can try it yourself by forking the library repo and applying the fix as suggested. If this doesn’t work, you can downgrade to the previous version of the library that works for you.
We will meanwhile try to find alternative solution to the problem you described. Will keep you updated.
“jdk.httpclient.allowRestrictedHeaders” is a new system property in Java, which can be specified on XP startup: with newer XP versions that embed Java 11.0.14 and higher. For instance via setenv.sh with
“-Djdk.httpclient.allowRestrictedHeaders=…” config line.
7.9.2 XP uses 11.0.15 java version, so looks like you can add the property for your current environment.
