I think we need to harden this area of code actually. Some JDK configurations may not have an SSL provider.

e.g. (removing JSSE from config)   


    See "java -X" for verbose security settings options
    Security provider static configuration: (in order of preference)
        Provider name: SUN
        Provider name: SunRsaSign
Exception in thread "main" java.lang.InternalError: Failed to create SSL socket
	at java.base/sun.launcher.SecuritySettings.printSecurityTLSConfig(SecuritySettings.java:121)
	at java.base/sun.launcher.SecuritySettings.printSecuritySummarySettings(SecuritySettings.java:75)
	at java.base/sun.launcher.LauncherHelper.showSettings(LauncherHelper.java:188)
