Sun released a few days ago an update to their JRE version 6 update 10. This update is of special interest to the ColdFusion community because it solves a renown bug when class loading cfc's. Usual behaviors for this bug on previous JDK 6.X was incredible slow performance on loading a highly used CFC application. I just updated my servers to use the new 10 update and everything flies! I highly recommend that you update your servers to use JDK 6 update 10. You can download the bits from here: http://java.sun.com/javase/downloads/?intcmp=1281

Speaker Featuring - Round 1
Every conference is more than the talks we see on stage it’s also the story of the people who make it possible.
With the first round of Into the Box 2026 sessions and workshops now live, we’re excited to introduce some of the speakers who will be joining us this year. These community members, practitioners, and Ortus team experts bring decades of real-world experience across CFML, BoxLang, JVM modernization, testing, AI, and cloud-native development.

Thanks for pointing out the update. I'll let everyone else go first and try it out in production and write up about it in their blogs. Got to be totally sure it doesn't introduce a new unexpected issue! :-) Does anyone know the Adobe line on supporting CF running a version of Java that didn't ship with CF?

Hi Gary, I did the upgrade last night on my production systems, so I will let you know the outcome. So far, I have seen performance updates because of it.

Hi Luis, Is there any documentation to assist with installation on a cf8 machine? I assume that the correct update for CF8 would be the JDK 6 Update 10 with Java EE. Thanks.

I did not find any but it is pretty trivial. 1 dowload the jdk and install 2 make a backup of the jvm.config file in (cfinstall)/runtime I believe 3 open file and modify the jew home to point to the jdk you installed. Remember to use backslashes 4 restart cf
