This is a follow-up to a post I did in late 2014, CF911: 'Help! I've updated the JVM which ColdFusion uses, and now it won't start!'
. In that post, I listed about a dozen common problems that befall people who try to update the JVM that CF is using (and it and this post apply as well to Lucee or BlueDragon, or indeed any Java application server).
In this post, I want to elaborate on one more common mistake. Well, mistake may be too strong word. It's about a default option when you run a Java JDK installer (see the other post for more on JDK vs JRE options).
In short, I make the case here for why you should NOT let the JDK installer implement its "public jre" option.
