Recent news from Oracle indicates that free public support (bug fixes and security updates) will currently only be provided for Java SE 8.x (as of May 2016). This is a smart move for Oracle for many reasons – one being an attempt to force users and developers to migrate away from old vulnerable versions of Java (the java plugin is a top malware target). Unfortunately, Oracle is still not providing a free capability to automatically update Java client installs to the latest security fix release.
Another huge reason to migrate ALL servers and client systems to the latest Java 8.x release – TLS and SSL cipher support compatibility. Recent industry migrations to new cipher suites and newer TLS versions are increasing security for Internet communications, but this is causing difficult-to-troubleshoot compatibility issues for Java 7.x and older which don’t ship with default support for the newer server ciphers and may leave newer TLS versions disabled.
Moral of the story … upgrade ALL your server and client Java installs to Java SE 8.x – the sooner the better. If you’re having trouble connecting with a Java client or server program, double-check which version of Java is being used – all clients and servers should be running 8.x for your best chances of security compliance and cipher/TLS compatibility.
For some technical details on cipher and TLS default support with each Java SE version along with troubleshooting tips, see the following Oracle article: Diagnosing TLS, SSL, and HTTPS. Good luck with your Java SE TLS/SSL tasks!
