Thanks Adobe CF team; Java 8 support available:

It is worth noting although Java 8 does not consume PermGen memory space since it is using Metaspace

you can have PermGen defined in your JVM Arguments EG -XX:MaxPermSize=192m. Java 8 will notice that as a syntax error and ignore it rather than not start ColdFusion (Java).

Cheers, Carl.

I'm also interested to know if CF10/11 will be patched to officially support Java 8.

Just received an email from FusionReactor announcing support for Java 8. Does anybody know the status of official CF10 support for Java 1.8 ?

With Java 8 release pending next month I thought I would edit this post. When will CF10 be officially supported on Java 1.8?

Thanks, Carl.

CF10 with Java 8

Hello,

Has anyone else tried to use CF with Java 8 preview? If you have tried Java 8 preview have you noticed anything interesting?

Something to share. Java 8 uses memory differently to Java 7 or 6 (reminder Java 6 is EOL). The non heap memory Permanent generation has been done away with and is now consumed in a new memory space called Metaspace. I guess that will mean CF folks will not see the dreaded “java.lang.OutOfMemoryError: PermGen space” in coldfusion-out.log anymore.

For interested readers here is my CF10 Summary part:

For those more curious about Java memory heap, non heap spaces and garbage collection here is a portion of CF10 verbose Java 8 log:

To have something to compare switching CF10 back to Java 7 with no other JVM alterations verbose log portion for similar usage says:

I should add Java 8 is preview and not officially support by Adobe CF so do not install it on your CF production or any environment that you rely on.

Java 8 release is expected March 2014. That might seem a long way off but like the previous Java 7 release can creep up on you rather quickly.

Regards, Carl.
