问题 I am setting up my web application in JDK11 runtime environment. I am able to bring my application server up in JDK8 runtime enviroment but getting below exception after switching to JDK11 enviroment. Exception : javax.net.ssl.SSLHandshakeException: Invalid ECDH ServerKeyExchange signature For SSlHandshake I am using TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 cipher suite Algorithm.

Btw, all other web servers work fine. So it's probably not related to my code. This error also occurs without any ssl/tls protocol restriction. Any ideas? The output with option "javax.net.debug=all" is as follows: DEBG getSecureScocket: Supported

问题 I'm having trouble with my java truststore. I would be very grateful if someone could help me with this problem. I've built a micro service with Spring-Boot for geocoding in which I want to use the Google Geocoding API.

Edit: This is the precise error message I'm

问题 I'm trying to configure websphere-liberty server to use default keystore and trustore for all outbound connections (actually REST calls) and for inbound use a custom key and trust stores.
