What is the “Unexpected end of handshake data” exception?

There is a known bug in earlier Sun’s Java JSSE implementations, which provokes a “javax.net.ssl.SSLException: Unexpected end of handshake data” message in the Lightstreamer log. This happens when a Firefox browser opens an SSL connection to Lightstreamer Server. This error is always recovered and no issue arises for the final users. But upgrading to a JDK version where the bug was fixed is suggested in any case. This bug was fixed in Java 6 update 12. See http://java.sun.com/javase/6/webnotes/6u12.html and look for bug 6728126.
