Issue Description
JDK-8237474

Default SSLEngine Should Create in Server Role


In JDK 11 and later, javax.net.ssl.SSLEngine by default used client mode when handshaking. As a result, the set of default enabled protocols may differ to what is expected. SSLEngine would usually be used in server mode. From this JDK release onwards, SSLEngine will default to server mode. The javax.net.ssl.SSLEngine.setUseClientMode​(boolean mode) method may be used to configure the mode.
