Upgrading Java JDK and Lucee manually vs installer on Windows

I’ve searched for my question, but didn’t get enough information to be sure.

We experienced some handshake failures with CFHTTP on certain SSL-Websites, Seems that it comes from Java 1.8.0_66. Upgrading to Java should fix it. Can someone tell me, if upgrading Java by installing onto the existing JDK-Folder works with Lucee final without problems? Can I also simply drop the lucee-jars into the existing directory to upgrade to last stable Lucee-Release without touching tomcat and its config files?. Or would it be better to make a total new, and complete fresh install with the installer?

We are running Lucee on Win installed with the lucee-installer (using tomcat/IIS and Boncode):
|Version|Lucee final|
|OS|Windows Server 2012 R2 (6.3) 64bit|
|Servlet Container|Apache Tomcat/8.0.28|
|Java|1.8.0_66 (Oracle Corporation) 64bit|

Thanks in advance.

Do a fresh install

Replacing the jdk folder will work too for upgrading java


Thanks for ultra fast answer!!!

Make sure your Tomcat is updated to at least 8.0.50 for security fixes. It is easy. Just copy the new lib files over. I updated my Linux by just copying over an updated jdk files and Tomcat lib files.
