java-11

The following code throws an error in JDK 11: HttpURLConnection con = (HttpURLConnection) new URL("https://sis.redsys.es/sis/realizarPago").openConnection(); con.setRequestMethod("GET"); con.getResponseCode(); The error is: javax.net.ssl.SSLHandshakeException: extension (10) should not be presented in server_hello at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:128) at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:117) at java.base/sun.security.ssl.TransportContext.fatal(TransportContext.java:312) at java.base/sun.security.ssl.TransportContext.fatal

Sometimes it is needed to allow insecure HTTPS connections, e.g. in some web-crawling applications which should work with any site. I used one such solution with old HttpsURLConnection API which was recently superseded by the new HttpClient API in JDK 11. What is the way to allow insecure HTTPS connections (self-signed or expired certificate) with this new API? UPD: The code I tried (in Kotlin but maps directly to Java): val trustAllCerts = arrayOf<TrustManager>(object: X509TrustManager { override fun getAcceptedIssuers(): Array<X509Certificate>? = null override fun checkClientTrusted(certs:

I know, it is duplicate question,but problem is new, Please do not mark duplicate question.

Inspired by question Why is the Java 11 base Docker image so large? (openjdk:11-jre-slim) I found that this topic in Java world is still not settled. As for 07 Dec 2018 there are common issues/pitfalls (discussed in the ticket above): JRE is not distributed as a separate "package". Modules from JDK should be used instead Oracle OpenJDK 11 doesn't support Linux Alpine , so lightweight images can't be easily created In the same time current stable Debian versions still doesn't have Java 11 packages ( Ubuntu has Java 10 installed under openjdk-11 packages), that's why unstable sid versions are

In the past, Oracle used to publish an executable installers for Windows that would: Unpack files Add registry keys indicating the installed version and path Add the JRE to the system PATH Register an uninstaller with Windows. As of Java 11, the Oracle's free version of Java ( Oracle OpenJDK ) doesn't seem to include an installer. It is just a zip file containing the binaries. How are we supposed to install OpenJDK 11 on Windows seeing as the aforementioned integrations are no longer there? Aren't they necessary? Lior Bar-On Extract the zip file into a folder, e.g. C:\Program Files\Java\ and
