Very slow generation of definitions files

[Jaime Metcher]

Hi All,

I'm finding that it's taking a looong time (anything up to 30 minutes) for transfer to generate definitions files.    Not sure where to start on this one - has anyone seen anything similar?  Is this just the JVM 1.6 classloader bug?  I'm on CF8.01 with the default JVM, IIS6, W2K3.  The top of the stack trace looks like this:

Welcome to the world of Java 1.6.

Once the .transfer files have been gen'd it's not too bad... but yes,
this is an aweful issue with Java 1.6.

Ouch.  Thanks for putting me into my misery :)

Update to the Java 1.6 RC 10 and the slowness will go away. It's been
in beta for ages, but it's plenty stable, now it's a Release Candidate
so you have even more reason to update! Our server has run it for
months, even while beta, without issue.

Thanks, Elliot.  I'll give that a go.

That's beautiful man, runs quite nice for local development here on Transfer/MG/CS site.  Speeds up reloads quite a bit!.  Thanks for the tip Elliott!

Elliott,

Am I correct in understanding that Java 1.6 will *not* work with CF 7.02? 

[Elliott Sprehn]

Yes. I've never been able to get CF7 to deploy properly on it. Usually
fails quite catastrophically with lots of errors.

I did get CF6.1 to deploy on Java 1.5 successfully with minor quirks.

If you're on CF7 and Java 1.4 though then you shouldn't have this
class loader bug that causes transfer to be sooo slow. Transfer
startup slowness on CF7 is usually just related to createObject()
being sluggish.

[Matt Quackenbush]

Okay.  Thanks.  Glad I remembered to ask before I did the update!  LOL  ;-)

[Nando]

Can anyone point me in the right direction how to update CF8 to Java 1.6 RC 10?

Thanks,
Nando
