SSL handshake alert: unrecognized_name error since upgrade to Java 1.7.0

Question

I upgraded from Java 1.6 to Java 1.7 today. Since then an error occur when I try to establish a connection to my webserver over SSL:

javax.net.ssl.SSLProtoco         


        

Answer 1

I have also come across this issue whilst upgrading from Java 1.6_29 to 1.7.

Alarmingly, my customer has discovered a setting in the Java control panel which resolves this.

In the Advanced Tab you can check 'Use SSL 2.0 compatible ClientHello format'.

This seems to resolve the issue.

We are using Java applets in an Internet Explorer browser.

Hope this helps.
