We have CHF2 on our 9.0.1 server plus alll post CHF2 security updates. Just the other day I noticed that a cumulative HF 3 and 4 were released and I must have missed these in early 2013 when they were released. My question is is a CHF2 server with all security updates equivalent to CHF with all security updates? Or did CHF3 and CHF4 get some non security related hotfixes and other enhancements?
I'm asking all of this as I'd like to get to the latest JDK 1.7.
And if I should update to CHF4 can I just apply that directly? Or are there possibly a few files in CFIDE and WEBINF or jars that were the non security related hotfixes?
