Java 6 EOL & Coldfusion

[Andrew]

If my understanding is correct, java 6 public updates cease in nov.

https://blogs.oracle.com/henrik/entry/updated_java_6_eol_date

Does this affect cf users / admins in any way?

I guess adobe have never officially supported every java minor version anyway, but are we vulnerable if a security flaw is found post nov and there are no updates available?

My understanding is that java 7 isn't officially supported? I've never tried it in any case

Andrew this thread maybe of interest:

Yeah, I think Rakshith's post can be read as: there will be a CF 9.0.3 and a CF 10.0.1 (or whatever numbering will be chosen) that updates your CF installations to Java 7.

Fun times, will bring another round of new JVM behaviour :) - but solve the Java 6 EOL issues nicely.

I know Carl has been running CF on Java 7 and so have I.  I've had a personal server ( linux ) running 7 since release and haven't seen any issues.

1.7.0_03 is working fine on my local copy of 9 in windows aswell.




I'm sure the jvm gurus will be able to take advantage of some of the new features including the new gc options.

Paul.

It will be interesting to see if CF10 > Server Update > Updates will manage the Java 6 to Java 7 change.

 
Indeed there are some JVM garbage collector changes to experiment with - Garbage First (G1), G1 being experimental option in some Java 6 and release in Java 7

[Kai Koenig]

Yup - we experimented with G1 in an earlier version of Java 6 and CF 8/9 and even though it was awesome conceptually, the JVM died multiple times per day during high load :-)

But I expect that to be much better in Java 7 now.

Cheers

Kai

Seen good 200 day + uptimes and no GC pause effect with G1 so long as allow sufficient RAM to heap.

[Andrew Myers]

Thanks for sharing Carl.

FWIW I have also had cf 9.0.1 running in test on Java 7 (deployed on jboss).  No issues observed thus far

That raises a couple of interesting points (about a possible “9.0.3”).

First, would such an updater work equally well for someone on 9.0 or 9.0.1 (which have Verity) as for someone on 9.0.2 (which does not have Verity)?  Of course, they will have to make it do so.

Second, this begs a question: for now we can know that someone on 9.0.2 does NOT have Verity. If there is a 9.0.3, we will lose that distinction and some needing to know such things will have to wonder “is this a 9.0.3 with or without Verity?”

Fun times to come, indeed. :-)

Yeah, I'm pretty sure it's much more stable now. When I trialled it, it was one of the first G1 builds in Java 6.
