Answer 1

Ran into this issue with spring boot and jvm 1.7 and 1.8. On AWS, we did not have the option to change the ServerName and ServerAlias to match (they are different) so we did the following:

In build.gradle we added the following:

System.setProperty("jsse.enableSNIExtension", "false")
bootRun.systemProperties = System.properties

That allowed us to bypass the issue with the "Unrecognized Name".
