The root of problem is support of Extended Master Key Extension in [https://github.com/openjdk/jdk/blob/jdk-11+28/src/java.base/share/classes/sun/security/ssl/ClientHello.java#L497.] The standard jdk HttpURLConnection doesn't be affected this issues because of it sets chc.sslConfig.identificationProtocol equals to HTTPS by default [https://github.com/openjdk/jdk/blob/jdk-11%2B28/src/java.base/share/classes/sun/net/www/protocol/https/HttpsClient.java#L560.] I tried to repeat the same trick (The commented code), but due to the bugs of JDK [https://bugs.openjdk.java.net/browse/JDK-8253368] and may be incorrect implementation of method BHttpConnectionBase.close it doesn't work. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@hc.apache.org For additional commands, e-mail: dev-h...@hc.apache.org
