We are using ColdFusion 9.0.1 with jdk 1.7.0_75 version. We have to use TLS 1.2 in our systems.
We have tried:
Added -Dhttps.protocols=TLSv1.2 line to JRun4 > bin > jmv.config file.
Installed jdk1.8.0_172 - jdk1.8.0_221 versions and changed JRun4 > bin > jmv.config > java.home path. After that when i want to open web page, opens empty page. It is empty between body tags. There is no error. I have read an article linked below, i can use ColdFusion 9 with Java 8 without problem.
I would try installing all available patches on CF 9.0.1 while you're still on Java 7, then try upgrading to Java 8. But ultimately, this is really old software and in the near future you're probably going to need to update to something supported.
